Jp u-lmos carrier group - JP Enterprises Complete JPBC Bolt Carrier Group (BCG) .223 Caliber

This BCG is flawless, light, and offers an impeccable cycle. JP states this BCG is not for duty. I have had no problems cycling any type of 300BO with this BCG. After 1000 rounds I see no signs of wear. Also using JP silent capture H2 and JP adjustable gas block. These are both a must to maximize this BCG's potential and longevity. Especially with pistol gas. The key is not to over gas this BCG and keep it clean. If done, I don't see any reliability problems. I am certain this BCG does not have the longevity of a tool steel carrier. But like many high end AR products, it is about pushing limits. For that you may not get duty longevity. For fast cycling, low recoil applications this is the best. Plus it's nice looking. In my opinion its duty life to dollar is worth the replacement and continuation of use.
