Most Helpful Positive Review Lightweight design reduces felt recoil
The LMOS design of this bolt carrier weighs 2oz. less than the standard JP bolt carrier, and while 2oz. doesn’t seem like much, it definitely reduces the felt recoil in my .308 Winchester Aero Precision M5E1.

JP BCG for ar10

by Brandon Smith, Verified Owner from CO, United States Written on April 11, 2025
This is one of the best bcg's on the market for ar10's. Lightweight, strong, and smooth like butter.. It's not full auto capible, but it does run multiple calibers like 6.5cm, 8.6blk, and possibly others. Looks great and functions flawlessly.

good quality

by kookiewarrior, Verified Owner from CA, United States Written on August 13, 2023
My second low mass bolt carrier from JP my first one was variable mass and held up well. Hopefully this is good too. The machine job is flawless and no scratches on the bolt itself, fits my spare High pressure 308 bolt carrier group. Wish it shipped with cam pin and retaining pin though.
