The Primary Weapons Systems ENHANCD STL BUFFR CARB H3 5.5OZ is a purpose-built buffer for AR platform rifles, delivering reliable cycling in 556 NATO chambers with a 5.5 oz H3 profile that sits as an intermediate option for shooters seeking a balanced recoil feel. Crafted from 4140 steel with a fluted body, this buffer minimizes contact points to promote smoother operation while allowing debris to clear more easily, and the FNC LIFE HD treatment chemically bonds lubrication into the surface for consistently smooth cycling under duty or range conditions. The MOD 2 design emphasizes durability and performance, pairing a heavy yet controlled mass with a robust construction that helps stabilize muzzle rise and restore proper gas system timing after each shot. Ideal for shooters prioritizing dependable function in dynamic environments, the H3 buffer excels in semi-automatic rifles that require dependable, repeatable cycling without sacrificing accuracy or control. Its 5.5 oz weight places it between lighter and heavier buffers, providing a versatile option for a wide range of AR-style setups while maintaining compatibility with standard rifle components and buffers designed for 556 NATO configurations.
