  1. decodedmessages (verified owner)

    Another great product from LMT Defense. The coating, rigidity, and overall construction makes this bolt carrier group one of the finest piston components in the market. This is the exact model used for the Estonia contract. So, if you’d like to ‘build’ an Estonia upper, or a piston variant, this bolt carrier group is a must.

    The piston-operated design of this BCG provides several advantages over a direct impingement BCG. It reduces fouling and carbon buildup, which can improve reliability and accuracy. It also helps to reduce recoil, which can make it easier to shoot for longer periods of time.

    The LMT FULL-AUTO PISTON 5.56 BCG G2 also features a captive firing pin retainer, which helps to prevent the firing pin from coming loose. This is a critical safety feature, and it is one of the things that sets this BCG apart from other piston BCGs on the market.

    Overall, the LMT FULL-AUTO PISTON 5.56 BCG G2 is a top-of-the-line piston BCG that is perfect for shooters who demand the best in reliability, durability, and performance.
    f you are looking for a top-of-the-line piston BCG for your 5.56 rifle, the LMT FULL-AUTO PISTON 5.56 BCG G2 is a great option. It is reliable, durable, and performs great.

    Do not skimp on the BCG in any rifle.
