It's only for when you're using a T8.1 magazine and a 12g co2. You won't notice a difference using the stock magazine. But a 12g co2 will blow out the stock oring on the first shot if the marker is turned all the way up.
Very good to know! It's surprising to me that the calculated 15% increase in power with the T8.1 magazine (based on size/#shots) could make such a difference.
well consider the upgrade to avoid blowout if you using it for self defense. id want to know if its a better material or less likely to blow out vs the stock o-ring.
With the stock o-ring the common blow-out is because people are shooting projectiles that are too light (such as pepperballs or paintballs) and there is not enough force pushing back the bolt. I have done a test shooting full power on the atom6 pickle and they are mega light weight. After 3 shots the o-ring blew out already. That's the problem with high power. If you shoot normal paintball power, it's fine and they won't blow out. This o-ring upgrade , yes it is better material, more fitting and does have a better seal to it. Much tougher material too. You can tell when you squeeze! So it is for sure better than stock o-ring and better for us high power users. Yet it wont magically add power to your gun
I was under the impression that if your gonna use the 8.1 mags with a 12gm on a fsc you should change the heat core o ring because it will blow the o ring not for upping the fps
If I'm understanding correctly, with your direct and nicely controlled comparison of stock magazine to T8.1 magazine with this high power setup, there really wasn't much change in average FPS. Maybe a very small increase at best from the larger size CO2. Other than 2 extra shots and cheaper cost, I don't see much evidence for greater power per shot. I guess the advantage only becomes evident at the very highest power, almost max?
Doesnt matter THAT much to be honest. I would opt for the 8g for "real" use because it is easier to carry. Normal use is 12g for the $ issue. 8g N2 cartridges will work better than Co2 in freezing temp like in the sub30C something like that in Canada...
Love the videos. Quick question: I installed the heatcore oring (new black one) on my fsc, and it fits so much tighter that the bolt doesn't slide around as freely as with the stock one. It felt so tight by hand that i thought it was a problem and put the stock one back without test firing. Is that tightness normal? It was well seated and oiled, i even tried with a second heatcore oring, same thing. I would think the bolt would want to slide as freely as possible to reduce power loss to friction Thanks
My fsc is always leaking out of the back near velocity screw once 12 g co2 is charged. I got told to get a prv delete. But I'm not sure . Could you make a video showing leaking in back and or the various fixes sir
Could be caliber size. Grimburg rounds are 8 grams @(0.686 cal). First strike rounds are 3.5 grams that are supposed to fit first strike barrels with a bore size of (0.683 cal).first strike is the paintball company, and Grimburg is the makers of the Heatcore O ring, and 8 gram rounds. You’ll need the correct barrel for specific rounds. Grimburg barrel for Grimburg rounds or find the correct barrel bore size.
Hi. On the 8.1/9.1 the milsig o-ring works very well to have more power and not blow out the o-ring, you can tune it very high after that without o-ring problems, check this, more than 50/60 joules : facebook.com/groups/846982325660103/permalink/882239068801095/

One thing I like about your videos is you cram so much info in them, you do not waste my time or yours. Well done and thank you.
Loving these videos ive been binging them since 2am its 3pm now lol. Thank you for all the things you have taught me so far!
man im loving this. you keep pushing it towards greatness.
You should show how to install the O-rings in the FSC.
would be nice
Grimburg has a video on how to do it.

Uh why the hell is that?? Please explain atleast briefly
I have both mags
What difference does a a magazine make?

There is a limit on how powerful you can make the FSC-The stock o-rings blow out.Gotta change them to Urethane o-rings to shoot past 50 joules.
Can you show how you put the new o-rings in? That would have been a much more suited video for the title you put. Thank Chin

Thanks
What happened ..did you fix it ..I want to put a new o ring in mine ..dont want to mess it up
The Milig Heat Core O-Ring blow under CO 2 Pressure to 1 Inch Diameter. Then he go out of the Firing Bolt. You can test it.
My fsc is always leaking out of the back near velocity screw once 12 g co2 is charged. I got told to get a prv delete. But I'm not sure . Could you make a video showing leaking in back and or the various fixes sir
Excellent information Thanks !
Oring change and grimburgs matched barrel
Power way up
How many complete turns did Yiu give the fsc
280 was huge.
yes we even got up to 290s lol... it's insane huh? With 8grams.. that's totally beating the breaker ball's record.
I did what you said. And now my gun is leaking immediately when i put the mag in the gun
Probably broke it, fixed it yet?
Is there a difference in first strike fsc or grinburg fsc? Or is it the same thing?
Could be caliber size. Grimburg rounds are 8 grams @(0.686 cal). First strike rounds are 3.5 grams that are supposed to fit first strike barrels with a bore size of (0.683 cal).first strike is the paintball company, and Grimburg is the makers of the Heatcore O ring, and 8 gram rounds.

What to choose (and why) for home defense: Tiberius 8.1 or First Strike? Answer please.
FSC, because no more T8.1 on the market
Is your t9.1 with 2× co2 adapter still your most powerful less lethal ?
So, did the fsc replace t8.1.
You actually do get a big increase
Hi. On the 8.1/9.1 the milsig o-ring works very well to have more power and not blow out the o-ring, you can tune it very high after that without o-ring problems, check this, more than 50/60 joules : facebook.com/groups/846982325660103/permalink/882239068801095/
yes it can but doesn't make sense to make it only do 1 or 2 shots out of a 12g co2. Will tune up with the t9.1 and hpa tanks later on for fun
Where do we get the Muslim o ring from.?
You can get the milsig o rings, (pack of three, although you'll probably only ever need one) at Grimburg Less Lethal
where do you buy the o rings?

@@Chiinnature thx bro, what do you mean is the max pressure that this pistol can handle, i am at 1200psi now.
🔫🔫🔫👍🍻🇺🇲
Hi
Chiinnature, do you have the complete description (name and part number) of the O-ring?
Will this O-ring also work in the T8.1 and T9.1?
yes it will work , go rockstartactical -
