3 simple tips learned about 60 years ago. Work on a soft white cloth (keeps parts from rolling away), fold cloth over work piece if danger of springs flying about, never try to catch a small screw / part - you may knock it far away - just watch where it goes.
First of all, I really want to thank you for putting this video up. 1 point of difference though, I think the firing pin should be secured with threadLocker. There is a tremendous amount of force on those threads, and they will loosen over time and potentially become damaged from the vibrations. Not using thread locker will risk the long-term integrity of the part.
In regards to HDR .50 power upgrades this is the most valuable/helpful video on RUclips. You should edit the title to include "valve removal" because it took me a long time to find this video (among all that I have downloaded) to remember which one talked us through "removing the valve block." Keep manning your post and providing this most valuable service. Michael in San Francisco.
You boast because you think you live somewhere cool. Don't you, Mister San Fran Temazipan man. Well, gargle my gherkin, I'm from L.A.... Little Altcar., Merseyside . Look where you leap, mate.....
Hi, thank you for posting the video, I’m struggling with getting the screws out, there quite small and the screws can easily round off when I try to get them out, any thoughts on what screwdriver works well?
When I started pistol shooting in 1979, 50 rounds of factory 0.45 ACP was £20. That was a weeks wages, I quickly learned to cast my own heads and reload ammunition. HDR 50 is not expensive.
*Congratulations friend, thanks for the video. Here in BRAZIL we are forced to go through endless bureaucracy to have a firearm to protect ourselves and we are resorting to this type of "weapons" but I am happy that there is the possibility of improving it.*
Hi Dog. Nicely done. What I find very very good is to keep the stock barrel and buy chrome steel balls 12.7mm 8.3g. But you need to tune the magazines. The power is brill. And because the stock barrel is just right for the balls, great accuracy at 10-15 yards. If you like a certain ammo, tune the magazine chambers to that ammo. It makes a hell of a difference. And save £100. So "Heavy Metal" not different size "grippy plastic/silicon". Can send you an example.
@@bucks09 Hi mate. Just make a sandpaper cigar and lightly sandpaper the chambers so that the balls feed in from the front. Just a light press fit. Snugg not tight. Enjoy.
Nice job, thanks. I'm late to this new game. I had wish that you'd have kept using the smaller weight ammo so a metric was established with only the upgrade being different.
Good steady upgrade Ben - not something that should be rushed with all those 'lively' springs involved 🤣🤣 nice result. Thanks for taking the time to film it all, I know it takes much, much longer than the end video length to produce this 😉💥
Only thing left now is to upgrade to an aluminium trommel. Another 3-5 joules as an estimation of gain. And, a squirt of the ole sillycoonspray never hurts lol. Good video Andy, and your right about that little trigger spring, they don't half fly. Lost mine during the 'fettling' and came up with a novel solution. Metal guitar string, wound into a spring shape, works a treat.
@@jimithesaintkl hello Jimi, if i recall correctly it was either the bottom e or the one above it. Took a few goes to get it right length,and try using a drill bit to wind the coil. I think it has made the action a little smoother. 36/46 gauge.
Thanks for the video! After an accident I am at home the next time and so I decidet to buy a HDR50 and a power kit, the tuning barrel arrives the next days and than I ll install the parts. Your video was the last I want to know before to start the job. Specially to left the pin which is glued was in my thoughts the biggest problem, a burner could be an option 👍 I hope everything will work fine and than I ll have some fun with the gun and maybe for homedefense too 😉
I should have watched this video till the very end! I bought the tuning barrel without watching any videos on it., I have a HDR.50. The tuning barrel I received was for HDP.50 ...Company mistake but the Pistol barrel and the revolver barrel are very different. But the pistol barrel will work if played with in the revolver!
A slight sugestion. Here at Ramstein AFB we use Tetra Gun (not an endorsement, I just have some at hand) fluoropolyner grease and with your thump if you evenly coat the sliding surfaces of the barrel and action (not the trigger assembly) evenly and lightly not only will your TDR50 cycle like velvet but you may obtain an additional 0.5~1.0 joules and a few extra MPS average velocity due to the extra gas sealing. Don't worry about cold thickening as this grease has a working range of -73°C to 398°C (-100°F to 750°F). Any fluoropolymer of this type will do with the same temperature range and thickness and they also work great on pew-pew and real steel slides also. Use less thick lubricants on finer areas as these greases tend not to migrate into tight areas. With new guns if Glock copper factory grease is used first for about 500 rounds then the other with standard use any wear in the future will be very minimal. But beware, Glock Copper makes a horrible mess so use it very sparingly. Unless of course you want everything around you to be copper colored. We do this with both our pew-pew's and real steel's at Ramstein-Meisenbach AFB and rarely if ever have we had a seizure due to wear. Lack of lube is a different matter. And always remember! "Once the bullet leaves the barrel there's no calling it back!". 👉🤪💨 To the Honor of my Ancestors, Capt. Tamre' Colby USAFE/NATO CAS/AS

umarex recommends to put 1 drop of RWS silicone oil on the tip of every co2 canister... RWS silicone oil is very expensive, can I use something alternative, what is your opinion of this
Looking back I see my statement was rather vague. What I meant was, can I use alternative brands of silicone oil or must it be only umarex brand RWS for umarex t4e, is RWS simply a marketing gimmick?
So just removing the valve block on the 11 Joules version would probably make some difference but Awsome Video and I see the difference with the tuning barrel
Thanks buddy! Good info! You could now put a HPA adapter on and use a 13c tank! I bet the joules would increase a lot more! And wouldn’t be affected by weather conditions.
just an idea, when you pull the metal parts apart, you could do it inside a bag, just so you dont have springs flying all over. -i have done so when modifying airsoft guns. liked you video, cheers mate :)
Am I missing something ? The "7.5 Joule" (which I've just ordered) shoots at 3.5J out of the box ? - less than 1/2 advertised power ?? That's shocking! I know different ammo gets different efficiencies, but that seems like grounds to send the thing back!
It’s very rare to really get out the advertised power on whatsoever airguns… Worst I’ve encountered was the SIG MCX CO2 pellet sprayer* (*because so inaccurate), It’s bragged a 12joules, but, on a hot summer day, just measured 5.8 J… And I bought even two of them, both the same, so I didn’t just get a lemon to be sent back !…
heat effects c02 quite a lot, warmer days more power, colder days less power. high pressure air conversions fix the problem but that's a whole other ball-ache to mod the the gun to work with a different power source.
I remember my dad buying me all kinds of mechanical toys ( electric cars, trains etc. ) and after a few days he would find them in pieces and question me, what happened to the toys? My response would always be, " I got tired of playing with them and so I decided to take them apart to see what made them work ".
Thanks for the videos I see how expensive it is to shot this ammo but I do reuse them and shot at target that does not damage the ammo. Why not try this?
me 2, i also use them again if not damaged. but the main use of this gun, is not to target shoot for fun, but defense, so the cost of ammo is not a factor imo. cheers :)
You need a Vice, my friend! even just a small one from Amazon, its not a man shop until you have a vice! Good job, I am going to do mine next thanks for showing everyone
I do have a vice, just waiting to sort my workbench out, the materials of which are being used as a platform for building the block wall at the back of the garage.
well produced. thanks. what about the torpedo by mercury rise? is it any good? are there kits for it? much to learn, and don't know where the discussions take place. any advice from anyone who can refer me.
So this is very interesting i bought a gen 1 and a gen2 hDr50 and TR50 both dont hae any type of valve up the co2 chamber? so do the upgrade kit just push up there?
So actually if in your country both the 7.5 and the 11 versions are available is better u buy straight away the 11 version? Or the 11version stock will give like 7 joules power? Because the 7.5v gave like 3 jouls? Complicated 😞
Hi Ben, can you do a video where you compare the modified 11j against this modified 7.5j? Doesn't seem to be much, if any difference from this test. It would be interesting to see them compared apples for apples. Many thanks
What you said about 7 joule UK version getting more gains than 11 joule version ? That doesn’t make any sense to me ? I’m in France and I can get the 11 Joule version, I’m contemplating the cal 68 version or this 50 cal version ? Which should I go for? Can you explain why a 7 joule version would get more power? I’d like to tune to around 40 J
That was the common myth at the time of recording, apparently the chamber inside the 7.5 joule version was slightly larger. I too am in France and my first HDR.50 was an 11 joule version, just managed to get 75 joules (I have a license) out of it using HPA. My HDR.68 (16 joule version) was hitting about 27-30 joules out of the box. A lot depends on what you want, the 68 is a big gun.
Great video content- keep it up! Hey what exact ammo were you using both them if you don't mind. Ive got the same thing fully done... Love to hear the comparison.... Thanks brother!
Thank you for this test Mad dog. Much appreciated. Is there some way you could diesel the ammo such as add vaseline to diabolo type of ammo like devastators? Would be very interesting to se if you get any effect and if so, by how much.
It sucks that we can't get tuning barrels in Greece. But what are they other than an extra cm. of threads? A smoother bore? A snugger bore that saves on leakage?
@@Maddogairguns Thank you. Since that's the case, it shouldn't be hard to have one machined at any shop. Come to think of it, it'll probably be cheaper too, eliminating shipping costs.
Really useful video..of course be interesting to know the difference just the tuning barrel makes on its own in the 7,5 joule..if you get the time lol ..great vid!
Hello! Thanks for your amazing videos. I have a question that I cannot solve. I want to buy Umarex HDR 50 11 joules for home protection. But I want to make this revolver more powerful. I watched a lot of videos, but I didn’t fully understand which of the options for increasing power is the most optimal? A revolver is needed specifically for home defense, and not for training or entertainment. I beg you, tell me a real way to increase the power of HDR 50.
I would suggest a 38 Special revolver then? If you already live somewhere where these high powered air guns are legal, a real gun should not be a problem?
most places where airguns have no limit and only require you to be 18 to buy them have severe restrictions on real firearms, you may be able to buy them with a "sports" use permit, but a carry permit is difficult or impossible, carrying an airgun even would also for a defensive purpose be illegal in most places! and although you are allowed to defend yourself, doing so even in your home with a legally owned firearm you need to be extremely careful to not end up serving a long prison sentence for it, your really need to be facing certain death and be able to prove it! your word that someone came at you with a knife might not cut it, actual stab wounds might be required to convince a court of law! a non lethal option might be better if it is capable of actually stopping someone but either way it will be a gamble! of course different countries have slight variations... imo a fully automatic high round pr second hpa driven bb gun with a 1000 round plus magazine might also be better for stopping an intruder than a 6 shot paintball gun... regular 68 cal paintball guns on a field are around 13 joules, so even if you double that you just might make an intruder really angry with 6 shots. a steady continuous stream of a 1000 plus 0.177 steel bbs to the face i think would be a better deterrent! but if you absolutely want this revolver then a 13c hpa tank conversion using 12.7 mm steel ballbearing balls would probably give the best result... hpa can easily be tuned to much higher pressure than co2, but then might become lethal at some point if you hit someone in the right/wrong place. edit: there is also the hdr68, a 16 joule 68cal 5 shot version. but i assume they are the same gun as the 50cal 6 shot 11 joule with just a bigger bore and the same potential for tuning and power. and im not sure but i think the 50cal might "hurt" more as the projectile travels faster and impacts on a smaller area, assuming they can be tuned to the same joule...
@@ralphbooger4756 not allowed to defend your own family or self? that is insane, good ol'AR-15 in 50Beowolf and the bad guy can not testify against you
Will it not do the same job just drilling the hole in the export valve bigger. Also I would like to know can the gun as standard shoot ball bearings or must u modify something.
I'm sure in standard form the gun will fire whatever you can fit in it, the heavier the projectile the more power you will need to get it up to speed. As for drilling the export valve, I have also done that mod, there is a video of that with the results.
The problem I'm having when I tighten my barrel extension all the way even very lightly the magazine spins I have to losen the barrel extension or remove it you had this problem what can I do
if you pull on barrel and depress the spring the mag/cylinder will spin freely ,just make sure your spring keeps the proper tension , and tighten barrel sections , you might want to use thread teflon tape so it tightens sooner so barrel can rest on cylinder !!!
The HomeDefence-24 barrel is not rifled,so to me is not worth the $100. My First Strike FSC came stock with the smooth barrel @ 30 Feet shoots an 8" pattern. After I installed the Lapco rifled barrel @ 30 feet a 3" pattern or Bullseye. My 7.5 Joule TR50(Same s HDR50) with the 7.5 Joule version valve kit from HomeDefence-24 Now it shoots a rubber ball thru a tin can @ 30 feet..
I might just go for the 11j version. Yes, it is more expensive, but with my hands containing 5 thumbs each, I know I will screw it up. Don't get me wrong, it's a great idea if you have the 7.5j version, and you do make the change look easy, but, going back to my hands of thumbs, easy or not, it will be a big challenge for me. Besides, increasing the joules by that much, and I'm only guessing here, it could change it from a non-lethal gun to a lethal gun. For those of us who don't want to kill an intruder and face court time, it might be best not to do the conversion. Just saying. Great video.
If you get the 11 joules version, you can just remove the valve block restriction for an extra 3-4joules. That is really easy, no need to mess with the springs in the trigger mechanism. Just split the case, take out the block and put i back together again.
ruclips.net/video/UYOBz4avQ14/видео.html This is about 13J+ Hdr 50,stopping power still insufficient. So you need this for home defend，you must use pepper ball.

Is it normal for a new hdr50 20 joules, to have a little burnt smell where co2 is at after shooting it? I started using Elite force silicone spray after the first 8 magazines I've only shot about 100 rounds so far. I'm hoping it just needs to be broken in. Appreciate any advice
I went on this home defense 24 looks like they only got upgraded for the 11j version when I have the 7.5j. Also why dose it only shoot like 4j on the first test if it says 7.5j by the manufacture.
Your never going to get what the manufacturer claim straight away. Here is the 7.5joule powerkit: en.homedefence-24.com/Collections/hdr-51/Products/powerkit-50-for-hdr50-export-valve-maximum-power-7-5j-16j?variant=32178585501814

How many shots per co2 cartridge are you getting now with all of these mods in place?
@@samfletcher93 Normaly goes back to 7.5 joule after 5-7 clips, so 5-7x6

Yes HDR50/TR50 can go "beyond multiverse" with hpa. Extremely powerful with hpa. Not only that, much cheaper to shoot with hpa and hand pump.

What would be the range of this now? Thanks in advance!
Would you be able to tell us the specific tools we need I had the HDR 50 turn up today and ordering power kit Friday but need the right tools
The confusing thing is the part that goes up the co2 chamber so it just pushes in? on the 7.5 jouls version?
well produced. thanks. what about the torpedo by mercury rise? is it any good? are there kits for it?
much to learn, and don't know where the discussions take place. any advice from anyone who can refer me.
I’m getting 18.7 j from the HDR with steel/rubber balls available online.
Damn near like rebuilding a 21 Jewel watch!
Is it possible (I'm assuming it is) to do only the tuning barrel change and still get a power increase without doing the power kit change?
2 seconds in i hear the english accent...And guns, i subscribe, same as me, born and bread 43 yrs...
Is your velocity in feet per second? If so it's only making 1.35 ft/lb which is well below the 6 ft/lb we're allowed in the UK.
If I have it set to read joules, it's metres per second.
so i working foot pounds as live in the states now. thats like 4 foot pounds of energy from a projectile the weight of a 22LR ?
So this is very interesting i bought a gen 1 and a gen2 hDr50 and TR50 both dont hae any type of valve up the co2 chamber? so do the upgrade kit just push up there?
Decent performance increase. But not really enough. Was expecting more with the barrel extension. I think the HDP shoots a bit hotter.
Ohhhhh it's a co2 pistol. I thought it was an actual fire arm for a second
So actually if in your country both the 7.5 and the 11 versions are available is better u buy straight away the 11 version? Or the 11version stock will give like 7 joules power? Because the 7.5v gave like 3 jouls? Complicated 😞
Hi Ben, can you do a video where you compare the modified 11j against this modified 7.5j?
Doesn't seem to be much, if any difference from this test. It would be interesting to see them compared apples for apples.
Many thanks
I’m hearing now, that there might not be much difference between the two, I’ll try to sort out a comparison video.
@@Maddogairguns cheers Ben, that'd be great. It certainly seems that way from your videos so far.
Yeah I'm really interested as well the differences between the two. Modded and unmodified as well as light simple mods
What you said about 7 joule UK version getting more gains than 11 joule version ? That doesn’t make any sense to me ? I’m in France and I can get the 11 Joule version, I’m contemplating the cal 68 version or this 50 cal version ? Which should I go for? Can you explain why a 7 joule version would get more power? I’d like to tune to around 40 J
That was the common myth at the time of recording, apparently the chamber inside the 7.5 joule version was slightly larger. I too am in France and my first HDR.50 was an 11 joule version, just managed to get 75 joules (I have a license) out of it using HPA. My HDR.68 (16 joule version) was hitting about 27-30 joules out of the box. A lot depends on what you want, the 68 is a big gun.
Great video mate thanks👍
UK gun law is insane
Great video content- keep it up! Hey what exact ammo were you using both them if you don't mind. Ive got the same thing fully done... Love to hear the comparison.... Thanks brother!
Sorry I missed it where you said the ammo 😢😅😂
Great Video Sir.
Thank you for this test Mad dog. Much appreciated. Is there some way you could diesel the ammo such as add vaseline to diabolo type of ammo like devastators?
Would be very interesting to se if you get any effect and if so, by how much.
Not sure it will work, I plan to give it a go at some point.
Did you do any more upgrades on these ? So you’re saying buy the 7 jule one is stronger than the 11 jule even if they both been modified?
What would be the difference when upgrading the 11j version?
It sucks that we can't get tuning barrels in Greece. But what are they other than an extra cm. of threads? A smoother bore? A snugger bore that saves on leakage?
The tuning barrel is made of steel, so harder wearing. It is also a snug fit for some ammo, making as you say less leakage of the co2.
@@Maddogairguns Thank you. Since that's the case, it shouldn't be hard to have one machined at any shop. Come to think of it, it'll probably be cheaper too, eliminating shipping costs.
That thing is kicking ass
Really useful video..of course be interesting to know the difference just the tuning barrel makes on its own in the 7,5 joule..if you get the time lol ..great vid!

Why is the little gas upside down?
Bonjour comment faire pour acquérir une carabine t4e hdr5o gen 1+2degass adapter merci beaucoup d'avance bonne journée
What's the fps conversion?
I was looking at the 11 Jules version would this kit work on that? Giving it even more power?
wow great tips. in this way is more power than a cal 22
Great vid bro
CHEERS fr Monterey
Cal..
good man u know your stuff
Which direcetion do i put the restricter back in? is it in the handle? but what direction?
20*C get you more power.
Its a inside the house revolver.
23-25 joule..I guess.
Hello! Thanks for your amazing videos. I have a question that I cannot solve. I want to buy Umarex HDR 50 11 joules for home protection. But I want to make this revolver more powerful. I watched a lot of videos, but I didn’t fully understand which of the options for increasing power is the most optimal? A revolver is needed specifically for home defense, and not for training or entertainment. I beg you, tell me a real way to increase the power of HDR 50.
I would suggest a 38 Special revolver then? If you already live somewhere where these high powered air guns are legal, a real gun should not be a problem?
@@penedrador I have a residence permit in this country, and I cannot buy a normal pistol yet.
most places where airguns have no limit and only require you to be 18 to buy them have severe restrictions on real firearms, you may be able to buy them with a "sports" use permit, but a carry permit is difficult or impossible, carrying an airgun even would also for a defensive purpose be illegal in most places!
and although you are allowed to defend yourself, doing so even in your home with a legally owned firearm you need to be extremely careful to not end up serving a long prison sentence for it, your really need to be facing certain death and be able to prove it! your word that someone came at you with a knife might not cut it, actual stab wounds might be required to convince a court of law!
a non lethal option might be better if it is capable of actually stopping someone but either way it will be a gamble!
of course different countries have slight variations...
imo a fully automatic high round pr second hpa driven bb gun with a 1000 round plus magazine might also be better for stopping an intruder than a 6 shot paintball gun... regular 68 cal paintball guns on a field are around 13 joules, so even if you double that you just might make an intruder really angry with 6 shots.
a steady continuous stream of a 1000 plus 0.177 steel bbs to the face i think would be a better deterrent!
but if you absolutely want this revolver then a 13c hpa tank conversion using 12.7 mm steel ballbearing balls would probably give the best result... hpa can easily be tuned to much higher pressure than co2, but then might become lethal at some point if you hit someone in the right/wrong place.
edit: there is also the hdr68, a 16 joule 68cal 5 shot version.
but i assume they are the same gun as the 50cal 6 shot 11 joule with just a bigger bore and the same potential for tuning and power.
and im not sure but i think the 50cal might "hurt" more as the projectile travels faster and impacts on a smaller area, assuming they can be tuned to the same joule...
@@ralphbooger4756 not allowed to defend your own family or self? that is insane, good ol'AR-15 in 50Beowolf and the bad guy can not testify against you
I need one of these
So why is the 7 Jule better to up grade than an 11 Jule...?....Great videos..
They say it is because the co2 chamber is larger on the 7.5joule version. But it might not make much difference.
@@Maddogairguns its true mate !!! :)
Good Video. You Did Some Good Upgrades. How Much Does it Cost?
Can't remember off hand, but there are links in the description for the parts I used.
@@Maddogairguns I Mean The Gun
Odd question...does a silencer exist for this?
Yes it does
It’s not as easy to get the thread lock off tho is it
Will it not do the same job just drilling the hole in the export valve bigger. Also I would like to know can the gun as standard shoot ball bearings or must u modify something.
I'm sure in standard form the gun will fire whatever you can fit in it, the heavier the projectile the more power you will need to get it up to speed. As for drilling the export valve, I have also done that mod, there is a video of that with the results.
great vid MDA
I think hdr 50 has 7.5 joule why your gun have only 4joule?
Where to get replacement springs or spring kit if lost springs?
Baffled by mine, the round “push” piece that goes up in the co2 chamber doesn’t stay in place and just falls out, looks like a loctite jobby
you need a o-ring on that piece
The problem I'm having when I tighten my barrel extension all the way even very lightly the magazine spins I have to losen the barrel extension or remove it you had this problem what can I do
if you pull on barrel and depress the spring the mag/cylinder will spin freely ,just make sure your spring keeps the proper tension , and tighten barrel sections , you might want to use thread teflon tape so it tightens sooner so barrel can rest on cylinder !!!
The HomeDefence-24 barrel is not rifled,so to me is not worth the $100.
My First Strike FSC came stock with the smooth barrel @ 30 Feet shoots an 8" pattern.
After I installed the Lapco rifled barrel @ 30 feet a 3" pattern or Bullseye.
My 7.5 Joule TR50(Same s HDR50) with the 7.5 Joule version valve kit from HomeDefence-24
Now it shoots a rubber ball thru a tin can @ 30 feet..
Hi I would like to know where you have got Lapco rifled barrel. Thanks
@@pabradeskaimas Lapco Paint Ball Company Los Angeles California .... All over eBay
thank you for clearfyinng if i had the 11 jl version do i need the cap
could you mod a brodax ,Too get more velocity sir.
Can you put an extender on an 11 joules to increase output?
I might just go for the 11j version. Yes, it is more expensive, but with my hands containing 5 thumbs each, I know I will screw it up. Don't get me wrong, it's a great idea if you have the 7.5j version, and you do make the change look easy, but, going back to my hands of thumbs, easy or not, it will be a big challenge for me. Besides, increasing the joules by that much, and I'm only guessing here, it could change it from a non-lethal gun to a lethal gun. For those of us who don't want to kill an intruder and face court time, it might be best not to do the conversion. Just saying. Great video.
If you get the 11 joules version, you can just remove the valve block restriction for an extra 3-4joules. That is really easy, no need to mess with the springs in the trigger mechanism. Just split the case, take out the block and put i back together again.
Hi,even though 50J+ still difficult fatal，Do not worry.
ruclips.net/video/UYOBz4avQ14/видео.html
This is about 13J+ Hdr 50,stopping power still insufficient.
So you need this for home defend，you must use pepper ball.
@@Maddogairguns do you have a video on this?
Good video. Not sure why you were only getting just over 3joules. My 7.5j version is always around the 7 joules mark.
It was fairly cold, which might explain the low readings.
@@Maddogairguns aww OK, makes sense.

Love this
Is it normal for a new hdr50 20 joules, to have a little burnt smell where co2 is at after shooting it?
I started using Elite force silicone spray after the first 8 magazines
I've only shot about 100 rounds so far. I'm hoping it just needs to be broken in.
Appreciate any advice
I've never experienced a burning smell from mine, I use Sonax silicone spray and never had a problem.
I went on this home defense 24 looks like they only got upgraded for the 11j version when I have the 7.5j. Also why dose it only shoot like 4j on the first test if it says 7.5j by the manufacture.
Your never going to get what the manufacturer claim straight away. Here is the 7.5joule powerkit: en.homedefence-24.com/Collections/hdr-51/Products/powerkit-50-for-hdr50-export-valve-maximum-power-7-5j-16j?variant=32178585501814
Id love to have one😮😢
Great vid thank you
The tube that holds my CO2 cartridge shot out how do I put it back in permanently
I have heard this happening a few times on the newer versions of the gun, best to get in touch with Umarex, as it's not fit for purpose.
got mine, chuffed with it ???
Can a 50 be modded to be more powerful than a modded 68?
