- Опубликовано: 24 дек 2024
- Rounding out this series on operating system components, we have, by far, the source of the most tech questions we field around here. Which Silent Captured Spring do you need for your rifle? A number of factors play into this, but it's simpler than a lot of people think.

Check out our new SCS Selection Guide! jprifles.com/1.4.7.2_os.php?menu_select=scs_guide
Everyone is complaining about the difficulty of the topic, but this video is the best supplemental source of information available...watching this video, in addition to a careful reading of the documentation JP provides on the website, does appear to answer all the questions most people have.
If I understand JP correctly with regard to selecting the proper buffer/spring combo:
- If the priority for a rifle is reliability, then increasing the buffer weight is the best initial approach. JP provides a flowchart to assist with this.
- If the priority for a rifle is recoil mitigation (in order facilitate the quickest recovery of the sights onto the target), then using a heavier spring with a lighter buffer weight might be the best initial approach. Sprinco claims to have empirical data to support this approach as well (they are a company that makes excellent springs...which could imply a bias...but JP SEEMS to substantiate this claim).
All choices have tradeoffs. It seems that the tradeoff for a lighter buffer mass would be a greater chance of the rifle failing to go into battery, and the tradeoff for a heavier buffer mass is increased recoil impulse (delaying sight recovery onto the target).
Based on the information available from JP and Sprinco, it seems that most rifle tinkerers need to understand the following (with various exceptions relating to poor rifle design/construction and weak magazine springs):
- If your rifle 1) reliably strips each round from the magazine, 2) the brass consistently ejects at 4 o'clock, 3) AND the bolt always locks back on the final round of a magazine, then your gun is gassed properly for that ammo. There's no need to modify it from there. In that case, you MAY want to get the JP SCS version of whatever you have in your gun if you really just can't stand the sound of the action spring during the cycling of your rifle.
- If you're going to be running a broad range of ammo types, then you want to make sure your rifle has the appropriate buffer/spring combo, in order to meet all 3 of the above criteria for the weakest powered ammo you are running. This means that it will be overgassed for some ammo, but it will always cycle with even the weakest ammo you use.
Thanks for the heads up. Took my 8” 300BO unsuppressed H2 for the first time. One fail to load. Bolt holds open on last rnd. But ejecting at 5 oclock. Going to try lighter spring but unsure.
Thank you. This complemented the video very well for me. Thanks for the breakdown
Very helpful explanation thanks
Super Big thankyou for that breakdown
@@Doc02864you have the h2 for a short 300bo? did you change any springs?
Just finished up this video. Probably the most important video for AR hobbyists to watch. Excellent job, gentlemen.
Update:. So I installed a tungsten weight on my SCS in my cloned LRP-07 that was unlocking prematurely running the VMOS BCG with SCS, 6.5CM 22in. Supermatch barrel, JP AGB, etc..
Completely fixed bolt opening prematurely and brass is coming out very clean now! Rifle is consistently locking back on last round and cycling great!
Thank you guys, THIS was the info I needed to get my cloned LRP-07 running reliably suppressed! Much appreciate!
Ben is the man!!! He helped me with my rifle order. Really knowledgeable and helpful !!!
That flow chart was exactly what I needed. Thank you!
I know the company says to use the H2 weight buffer for a suppressed SBR but I found that the bolt catch wouldn't lock back on an empty mag, even with a wide open adjustable gas block. I suggest buying the least expensive SCS as it may work just as it should and you aren't paying extra for some tungsten weights that may not be needed. I wish I did that. 😑
Made the same mistake lol
How to make any standard ar15 feel like a much higher quality rifle.
How is this better than say a Geissele buffer spring?🤯🔫💸
@@KaneGregory thats a good question 🤔 I wish I knew
@@KaneGregory IT doesn't rub against the buffer tube by design.
Either my comment in your last video on large frame BCGs was just coincidental timing or you guys went over all the info i was asking for but instead of responding you guys made a video!
Thank you very much for this, looks like I will be ordering a couple tungsten weights for my LRP-07 clone I built running a Omega 300 with JP 6.5CM barrel, JP detent AGB, VMOS H2, and SCS H2 and also have the spring kit.
I threw the lightest spring in this past weekend and retuned it to lock back on last round. Carbon on brass is really bad with either springs so GREAT info! Thank you guys, much appreciated!
good to know my intuition was right on. running a 2a palouse lite rifle with an icrw G3 low mass steel bolt. ordered the scs2-15 with a spring pack for further tuning. also using a superlative arms adjustable gas block. after my modifications, the rifle will be sitting at around 4.3 lbs down from the stock 5.3 lbs. With a scalarworks mount and aimpoint t2, it'll be at 4.7 ish lbs, with a huxwrx 762ti, it'll be back to stock weight of around 5.3 lbs (and i have an h2 captured spring in my PWS, but i don't think it'll need it because of the flowthrough nature of the suppressor).
Dollar for dollar lighter than a vseven while maintaining a forged receiver set, sitting just above 5 lbs with a dot and suppressor.
Great info. Trying to get my ar from 1 o'clock to 4 o'clock ejection of brass
Look at the JP silent captured spring if you want to take your build to the next level
How do I double like this video? Great information! Really enjoyed the the in-depth specifications!
I have both Arma spec and JP silent capture and I can't tell any difference between either one if you long as you have one of the two you're doing great..... if you can afford a JP that's great, if you can only afford Arma spec you're still doing great
I have a small frame 8" 300blk suppressed and law folder. Yikes my head hurts lmao 🤣
I have bought 2 then used them in the AR 15 uppers in 7.62x39 - 17 Remington - 223 - 6mm x45 they are no different than using the buffer and spring set up.
Still makes noise also .
no shit it makes noise
So there is no difference between the stock buffer and spring and this one on the 7.62?
It factually cannot make as much noise as a buffer/spring combo. The sprint is bent up and scraping all the walls of the buffer tube at all times. With this system, that no longer happens. It will rub a bit on the capture rod but not nearly as much as rubbing the buffer tube.
My 14.5 mid length Noveske needed the ar10 springs to cycle at the 3:30-4:00. Using on different platforms it seems like the springs are lighter than normal
Love the video but still big opportunities for more detail here. I have 3 JP SCS, and 2 of them are in the 300blk suppressed SBR and pistol. The SBR has a Law Folder on it, and the piece that adds the extension is right at 1oz; so, it is bumping you up a full buffer weight. So if you have JPSCS-15 and throw the Law extension on, you now effectively have an H1.
With 300blk, you are gas poor a lot of the time with subs; so, I would love to see 1) even lower powered springs and 2) more advice on how to tune with low backpressure cans like CAT, PTR, Hux, etc. 300blk is pretty much confined to pistol length gas (some micro out there); so, recommendations based on can and dwell time for barrel length with a specific 300blk spring kit would be amazing.
I’m not saying the only value to the SCS is the reduction/elimination of “sproing,” but that is a big reason to consider the SCS over significantly less expensive and interchangeable traditional buffers and springs. Solving for that part of an ever-growing market of suppressed 300blk short barrels seems to make a lot of sense.
Oops. Started out with all no’s for the jpscs2-15 and swapped into another rifle. no issues even though that has a shorter barrel and suppressed. 😬😬
If
2 steel, 1 tungsten = H
1 steel, 2 tungsten = H2
3 tungsten = H3
Then what is the H rating for the all 3 steel rings that come in the JPSCS2-15 package?
I have a 16”, 5.56 non-adjustable gas block and I want rapid cycling for rapid firing without the heavy recoil. Which configuration will work best?

What setup did you go with on the weights if you don't mind me asking? I'm building a 16" and like to be able to rapid fire with least amount of recoil aswell. Thanks in advance
Very informative.. great knowledge..👍🏼👍🏼
great video! Actually learned a thing or two, thanks for that. My current sbr build is on the verge of "dude you're doin way too much" and a killer battle rifle if i could iron out the kinks. Its a billet 5d tactical lower, machined by me, 11.5'' 5.56 nato upper, carbine length gas system w/adj block, billet slick side receiver, skeletonized lightweight Browning BCG, 7''x1.5'' modular can aslo machined by me, fostech echo sport trigger, and a standard carbine buffer and spring. shes slightly overgassed, but only during high fire rates in the echo position (which is screaming fast btw with this setup) and occasionally fails to pick up the next round from the mag, click empty chamber. i love the concept of the scs and im hoping you have a recommendation or 2 as to which kit and if itll help it be a little closer to reliable. thanks
Lol just started using a 5d jig and router myself xD got like 3 different builds half put together now haha
@@rachelstephens3680 From my experience, 5d's router setup is about as reliable as it gets when it comes to the finished product and machining accuracy. As long as I keep from doin something stupid, I know once I put a fresh blank in the jig it's going to come out ready to assemble without any headaches.
So I have the radical firearms ar15 mid length gas system. 16in barrel. Chamber in 556. Any idea what I should run? I’m just a little confused on all of this lol. I am assuming just the JPSCS2-15 but I don’t want to run into any issues. Anyone have any suggestions?
My h2 buffer is awesome!
A PCC buffer/captured would be nice. Especially if one was 1cm longer than standard carbine unit.
This is ridiculously helpful, thanks guys.
How about providing a link to the flow chart? The link in the notes above goes to a list of all the buffers but no flow chart (that I can find).
Flow chart is about half way down the Selection guide. jprifles.com/document_pdfs/SCS%20Selection%20Guide_880.pdf
@@JPRiflesGot it. Thanks so much.
I installed a JP "standard", My AR 15 began to "double feed - one in the chamber and one in the bolt chamber. I do have an Adjustable gas block on the gun before installing the "standard" JP..
Would that be from serious "Bolt Bounce", causing the bolt to slam forward so hard, it bounces back far enough to feed another round? Is this scenario caused by the spring being too stiff, weight being too light, or both? Did you find a solution? Thanks in advance for any replies. Cheers
I am having issues with some rounds not chambering completely using the standard captured spring. I ordered a couple of tungsten weights to see if that helps.
Make sure your scs moreso your buffer tube is installed far enough into your lower. Depending on that info you might need to thread the buffer in a turn or two, could even throw a quarter in the buffer as a shim to move the scs so it has good contact with the BCG when closed
ok ..do you have to remove the bolt carrier weight .. what the best weight for a 9mm direct blowback system ?
Yes, the slide passes through the rear of the bolt, so the 9MM bolts with weights will need to be removed. The weight required changes according to your setup. Give us a call and we can help you find the best for your setup. 651-426-9196

what about a 18" SPR with Rifle Length Gas System and with a Carbine Length Buffer Tube. Start with H1 ?
Thank you 😊
Ammo used in this was Hornady Black 208 grain A-Max (Subsonic) & It's a Custom Built AR Pistol I built from top to bottom.
My issue is I got one of these for my 10'' 300 blk out, in H2 weight config. My plan is to suppress it at some point. HOWEVER, if you dont supress it with the H2 config (2 titanium, 1 steel) EVEN with a adjustable gas block. I could get it to extract the shell casing but not rack another round without having to manually do so.
I'm guessing this is a spring issue as in spring weight is to heavy? OR is it i can use the spring that came with it and i need to use 3 steel weights so its standard until i suppress?
Very frustrating day at the range.
AFTER watching more of this video I'm seeing its a weight issue....thank god I ordered the SS Weights yesterday and I'll be changing those out to run subs even though at this time I'm not running it suppressed just yet. I also already have the spring set cause i bought it with the scs when i got it. So I'll start with the SCS Weight change to 3 Stainless to try and get the bolt to rack another round and achieve lock back (without manually locking bolt to the rear). If need be like you said do a 95% weight spring and go from there. THANKS!!!!! Helps out a lot!
Good explanation , tganks
So running with s 11.5 barrel i need a h2? Just play with the springs to see what best fite my liking?
Looking for a Silent Capture to go into my HBPDW for 300Blk. Any suggestions?
What about 9mm? Want to upgrade my Aero EPC for competition. Do I need a JP BCG or is the Aero EPC BCG ok?
JPRifles! QUESTION!
Will you eventually make one that works with the folding adapters like from Sylvan Arms and LawTactical? From the way they seem to work I didn't think they'd work with that plug being in the way. Thanks! ✊🏼🇺🇸🇺🇸🇺🇸
These are an absolute NIGHTMARE to take out of the buffer tube!
They have their own detent to fix this
A small pick works great. Harbor freight 2.99 4 pack the straight pick just bend the end a little , and it's a breeze.
One thing I'm not sure I understand...when is bolt bounce an actual problem on semi auto rifles?
Bolt bounce will topically move the bolt out of battery just enough so on the next shot you get a light firing pin mark on your primer and you end up with a misfire.
What do I need for a DD Mk18 and RC2 suppressor and a folding Law T pistol brace? 10H or the 15H?? I ordered a sprinco blue and a H2 buffer and then saw this. I was going to use the stock carrier that is at .70 but need to know if you guys suggest an adjustable carrier bolt or something else. I want to able to run both unsuppressed and suppressed as cleanly as possible. Semi auto.
I believe you are looking for the H2-LAW. It sounds like a specific request, reach out to tech@jprifles.com.
Should I get the h2 if im also getting a low mass bolt carrier for an ar-10
I just got mine in but now I'm questioning if it's the right one. I'm running a 16 inch with an h2 currently, suppressed and a radian suppressor charging handle. No shorty stock but standard buffer tube. The only difficulty saw was the polymer end am I wrong?
My Carbine buffer (Savage MSR15 Patrol) weight is 2.8oz. My brass is being tossed closer to the 5 O’clock position than 4-4:30. Should I go to a H or H1 Buffer? All I shoot is NATO spec 5.56.

Which one do you recommend for a faxon light weight BCG?
Also, would I need an Adjustable Gas Block as well as the JP buffer spring for a lightweight BCG or would the JP system be all I need?
What spring would yall put in a maxim defense pdx with a frt trigger?
What product show I select for a 16" mid length .750 fsb gas block and a2 birdcage(5.56) also using areo precision bcg and as for ammo used it's. 55 for range with friends and 75-77gr when using rest of time

I just ordered a JPSCS2-10H2 and spring kit for an 8.6 Blackout carbine build (16" barrel). I used a Geissele Super 42 spring and H2 buffer. I didn't install an adjustable gas block. I have one so if necessary I can change out the gas block. It ejects but dents the case mouth, the case lands at about the 1 to 2 o'clock position, and the bolt doesn't lock back on the last round. I weighed the buffer and it weighs 4.3 oz. My form 4 for a Dead Air Primal is at least 6 - 7 months out based on current status info. I plan to shoot this suppressed all of the time but shooting the Gorilla Ammunition supersonic loads, or my reloads, aren't off the table. The info on your site says the weight is 6.6 oz. Is that assembly weight or buffer weight? I'm looking forward to trying your system.
What's the lightest buffer weight you can configure it? I'm currently running a 1.7oz buffer. Rolls the brass out in a nice neat pile about 2' from me at 4:00. I have run a .59 oz buffer but never could get the bolt velocity low enough to feed reliably.
What about gas operated ARs like the DDM4 v7 from Daniel Defense suppressed? Would the small frame 15H2 be the correct one even though it’s a gas operated rifle?
Yes the 15H2 (JPSCS2-15H2) is the model we would suggest for that rifle with a suppressor.
which do I use for 10.5 300 Blk with Law Tactical folding brace
What bcg and buffer from this company can I run in my Daniel defense Dd5v4?

Hi, I'm wondering what setup you ended up with if you don't mind me asking? Building a 16" aswell thanks in advance
I have a 8.3" 300 blackout. Running subsonics mostly suppressed but would like for it to run unsuppressed at times. What buffer weight would you recommend?
you need the standard scs 15, id get the extra springs as well for further options.
JP flow chart says H1
What about adding weight to the bcg? In combination with the buffer system
We already have that option with our VMOS bolt carriers.
Excuse me, my ar15 is LWRC IC-A5, the original buffer is an H2 one, which item should I choose is better?
i have a suppressed 10.5 with a silencerco specwar. it gases me out like crazy gets in my eyes chokes me out. i have your JPSCS2-15K-H2 kit with the lightest spring installed on it. my gun runs with my adjustable gas block open 1 click away from fully open if i go 1 click more closed it dosent run. should i get a heavier buffer or put a heavier spring in it. id love to bring that gas down to where im not getting so choked out i can only run half a mag before my eyes are burning.
What's the has port size?
Did you figure out your problem? If so what was the fix?
Where can I find this jp flow chart? Can't seem to find it with Google
Thanks for a very helpful video. What temperature to heat the allen head screw to melt the loctite?
Go to Loctite's website or Google it. Since there are several varieties of Loctite, each one has its own procedure for removal. Example; Blue doesn't need any heat to remove it and is considered temporary. Red does need a certain amount of heat in order to remove screw/pin/etc.., and is considered permanent. There are other colors that represent different attributes according to environment they are used in. Example; high heat/damp/water exposure/etc.. I would start with the Red Loctite removal temperature and go from there. You can pick up a marker style pen that's called a "Temperature Stick". They are found at welding supply stores, (maybe hardware stores too), that will only melt at set temperatures, whicheavea a mark on the item once it reaches that markers set temperature. If you get a 200 degree marker, it will begin melting/marking the item once it reaches 200 degrees. They are very cheap in case you don't have a infrared thermometer or other devices to check temperature readings. I would recommend getting another temp marker that's 50 or 100 degrees less than the set temperature you need. This is just so you can have an indication of when you are getting close to your set temperature, preventing you from overheating the item any more than necessary. Sorry it turned into a book, lol, but it may help others. Temperature Markers are basically unknown to the mass majority. Cheers
**SPELLING CORRECTION**
"melts at set temperatures, WHICH LEAVES a mark on the item...." ** NOT "whicheavea a " .lol. wtf? Sorry bout that. Lol
Question, does this spring/ buffer lesson the amount of recoil ?
Yes- How much depends on caliber and rifle setup. Give us a call and we can help further 651-426-9196
Is there an option so if I'd like to swap from suppressed to non suppressed without having to switch the buffer or have another one of these on standby? Honestly not the biggest fan of the old fashioned flexing all over the place buffer springs and like how this system is a solid piece that isn't going to flop around if anyone has any idea what would work best honestly I don't care about recoil or anything like that regardless of recoil or anything else I just man handle the shit out of my rifle to the point the end of my shit ain't gonna move regardless if I'm shooting .22 all the way up to 308win. Like I said I just want all of my equipment to be solid and not warping everywhere and the way this one looks honestly looks solid enough I could cut an area out for it in my rifle case to set it in there if I need to buy 2 I guess I can have 2 different cut out sections and find a way to label which is which.
No need to switch back and forth, you can tune the gun to run with or without the suppressor.
Best spring to cycle supers ?
Can you use this on a fostech ARP 556
What spring power to go with on the jpscs?
My friend has a adams arms non adjustable mid length piston AR in 14.5” with adams lightweight carrier that reduces the bcg weight by 2 ounces compared to a milspec bcg. Should they just use the ejection pattern chart to make a proper buffer weight and spring combination? He is looking to reduce recoil and is wondering if paired with the lightweight bcg if you go with h2 buffer with standard spring or go lighter buffer weight and/or lighter buffer spring as well. Any input is greatly appreciated! I’m thinking h2 with the 80 or 85 spring due to the lightweight bolt carrier?
Not enough talk about the large platform. Cool video though. I love JP products
Is there anything that makes this family of rifles not annoying when using earpro. I HATE boinging bullets.
What actually does the buffer do , what are the benefits ??
Thanks 👍
It eliminates all the extra friction of the standard buffer spring scraping along the inside of the tube. So, shooting with it is smoother and less noisy. It's also reconfigurable and tunable so you can dial in the buffer system for your particular rifle as well as tweak the cyclic rate to what you like.
@@JPRifles ....I may check 1 out and I'll call for expertise help with my rifle specs ...
Thank You
What do you recommend for a Ballistic Adavantage 14.7 inch barrel on a rifle geared tword duty use, with Federal 55 grain Tactial bonded? Don't care about the noise. A soft shooting gun would be nice, but it's secondary to reliability. I'm assuming the barrel isn't short enough to qualify as an SBR.
I'm looking at acquiring a 300 HMR. It mimics a 30-30 WIN. What would you suggest for a spring rate?
what about .45acp suppressed with an 8in barrel?
My bcg cycles, ejects and locks back flawlessly but when I rapid fire it I can only get 5 or maybe 6 rounds off rapidly before it pauses. The bcg is forward, round is chambered but I get to 5 or 6 fast trigger pulls and the next fast trigger pull nothing happens but then the very next fast trigger pull it fires. It’s like it skips a trigger pull ever 5 shots approximately. Normal shooting it fires the entire magazine flawlessly. What is causing this to happen?
It’s an LWRCI 300 black out shooting 110 grain with the stock H2 buffer and spring. I’m firing as fast as I can pull the trigger when this happens. It’s a new AR so if anyone knows please tell me what I can do differently, thank you.
Did you ever figure out your issue?
.458 socom running 350gr to 405 grain full power handloads.

Are you shipping to Illinois?
We cannot ship and AR-15 or AR-10 style parts to Illinois.
What about rifles with an A5 recoil system?
We make an A5 spacer that you would use with the Silent Captured Spring system.
Can i run one of these in a HBPDW from SB tactical?
Look into the maxim pdw brace / stock. Jp and maxim have a proprietary silent capture spring system for that.
Has anyone actually sound tested these setups? Assuming you’re suppressed and subsonic do we actually have data that proves the overall sound of the action is quieter with these? And like quieter enough to be more ghostly than the next guy.
We test everything!

Why can’t you guys just do a video showing these systems NOT explaining it because explaining it isn’t helping. I’m the type of guy that needs to see it….. also you seriously need to start with the LF rifles. You say ultimately its the users parameters I guess maybe this system was a bit to advance for me. I own the SCS and the JP BCG to for my 308 AR but I just don’t know enough about it to trust it enough. Also is it normal for a 500+ dollar BCG to have the finished come off after the first cleaning????? Because I swear I have a brand new JP BCG with 5 rounds on it I still have all the original packaging and the DLC finished came of the dam thing wth is that???? Actually I think I’m going to do a video about this issue myself.
Interesting. Make the video. I want to see this.
Sounds like a lot of issues. Heating bolts. Multiple parts. Screwed together. 😩
