The JP Enterprises 9mm AR Bolt Carrier Group is an enhanced 9mm bolt carrier group that includes a Silent Captured Spring System for a heavier, more reliable bolt operating system. These Bolt Carrier Groups by JP Enterprises have a reduced stroke length which results in a faster firing impulse. This JP Enterprises 9mm AR Bolt Assembly is designed for optimal function with JP Silent Captured Springs for a heavier operating system that reduces bolt bounce while greatly improving reliability and accuracy. With a tighter firing pin channel, this bolt reduces pin wear which results in longer life and more reliable firing. The last round holt open feature is compatible with short-stroke Silent Captured Springs, allowing this bolt assembly to provide reliable last-round lockback with any compatible receiver such as our GMR-15. Install the JP Enterprises 9mm AR Bolt Assembly w/ Standard Silent Captured Spring onto your compatible receiver to update and enhance the 9mm operating system in your gun.

The JP silent capture spring for PCC 9mm is phenomenal!! And the BCG is ridiculous, this combo is a must have if your building a PCC. I have a couple other AR platforms running rifle calibers, and I like this setup so much I will be purchasing another 2 SCS and BCG.

Hands down the BEST bcg and buffer system EVER. J.p. enterprises does all the homework for you. The cycling is super smooth. The reliability is now second to none. I suggest this to any one wanting to boast about how great their AR shoots,and performs.

I decided to go with this setup because I wanted my AR9 to function flawlessly. I went with polished stainless steel BCG which is super smooth and well engineered. The only drawback for me was the price, but if you want the best, its going to cost you.

Bought this for a PCC upgrade, and it lived up to the hipe.Dropped in, and did not need any tuning running 147GN handloads at PF of 135.I can shoot as fast i can pull the trigger, without issue. (Previous buffer and spring set up took a lot of tuning, and still had occasional cycling issue).It also feels like there is less muzzle lift, but hard to quantify, as i only shoot with in 50 yards, so it was pretty accurate in both configs.Its a little pricey, and is why initially on this build i went the traditional set up, (bolt, buffer,and spring).Ultimately, it would have saved me money $ vs buying conventional buffer, spring, bolt, set up, then upgrading, if i just started with this.However, it being a gun i shoot in competition, i had a few cycling issues, that cost me score. Ultimately, i upgraded to this and have not had another failure, (al least not due to cycling).Would highly recommend.
