From the manufacturer

Modern technology meets "tried and true": K-SPEC buffers utilize an innovative captured compression system to absorb recoil and minimize muzzle rise - without any complex or expensive parts to wear down and fail. Paired with KAK Industry's flatwire spring, you have a simple drop-in replacement that eliminates bolt bounce, flattens muzzle rise, and smoothes out recoil. KAK Industry developed our K-SPEC buffer system to offer the best value in recoil mitigation, 100% made in America for a lifetime of dependable use. This kit includes an A5 length K-SPEC buffer, flatwire spring, and buffer install tool. Please note: This is intended only for use in A5-leng Mfg: Kak Industry Llc.
