Most Recent Reviews Very good BCG by Question-asker, Verified Owner, December 19, 2023
I have never had a single feeding issue across about 500 rounds, this barrel in an EPC9 performs very well. Rear weight can be removed exposing a standard sized hole in the rear side of the bolt carrier group.

Product Info for Jacob Grey Firearms 9mm Bolt Carrier Group (BCG)s

The Jacob Grey 9mm Bolt Carrier Group BCG is purpose built for AR-15 pistol caliber carbines that utilize Colt or Glock style magazines. This 9mm BCG features a removable weight and is full auto compatible. The AR-15 style extractor is machined from a billet of steel for improved reliability and durability while the stainless-steel firing pin utilizes a standard cotter pin for ease of disassembly. The JG 9mm BCG also features an integral carrier key for the charging handle to interface with. To add, it features a Black nitride coating to improve the hardness and smoothness of the surface making it reliable and easy to clean. Due to the increased rearward velocity, blowback AR systems require a heavier carrier. The JG 9mm bolt comes in at 14.8 ounces, providing the correct weight needed to tame your blow back system. Check out the Jacob Grey 9mm BCG for your next premium AR rifle or pistol build.image
