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 and A5 buffer tube, you have a complete buffer package that eliminates bolt bounce, flattens muzzle rise, and smoothes out recoil. KAK Industry developed their 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 a 4.7oz H1 K-SPEC buffer, flatwire spring, A5 buffer tube, and buffer install tool. Mfg: Kak Industry Llc.
