Ryan's Review of JP Enterprises Complete JPBC Bolt Carrier Group (BCG) .223 Caliber
Both are outstanding and butter smooth. Match yours to your use case - it’s very important.
I have a full mass BCG’s in all “must be reliable” rifles. Love them. No complaints and I highly recommend.
I had low mass BCG’s in two rifles, removed them, and swapped them for the JP full mass BCG’s. When sending the bolt forward from the bolt locked to the rear (empty mag / new mag scenario), I was getting a failure to feed or jam 100% of the time with a low mass BCG. The low mass didn’t have enough mass to push the 77gr bullets into the chamber properly is my guess. I also didn’t notice a different in recoil between the low mass and full mass. Regardless I’ll take reliability over possibly improved recoil, so the low masses are getting sold.
