The shock-absorbing polyurethane buffer is an innovative solution designed to replace the traditional bolt stop pin, effectively eliminating metal-to-metal contact within your firearm. This advanced buffer significantly extends the life of your receiver by cushioning the bolt's rearward motion, thereby reducing the risk of receiver cracking. Additionally, it minimizes felt recoil, providing a smoother shooting experience and ensures quieter cycling, enhancing overall operational stealth and comfort. This enhancement not only preserves the integrity of your firearm but also elevates your shooting performance.
