The Pws Enhanced Steel Body Buffer Carbine H2/308 from Primary Weapons Systems delivers reliable, smooth cycling for .308 applications with a purpose-built MOD 2 4140 steel body buffer featuring a fluted design that minimizes contact points to help debris clear quickly, while the FNC LIFE HD treatment chemically bonds lubrication for sustained, quieter operation. Weighing 4.4 oz, this buffer is shortened to work seamlessly with AR-10 platforms using standard buffer tubes and is designed to pair with the MK2 series, including complete lowers and rifles, ensuring a cohesive upgrade path for established systems. Engineered to reduce recoil impulse and improve take-up, the enhanced steel construction provides durable performance under demanding field and range conditions, making it an ideal upgrade for serious .308 shooters who demand consistent cycling, reliability, and reduced heat transfer during extended shooting sessions. Whether upgrading a factory setup or building a precision-oriented AR-10 platform, this buffer offers a balanced blend of weight, strength, and lubrication that support smoother operation, faster follow-up shots, and improved overall reliability in a wide range of shooting environments.
