KAK K-SPEC Buffer and Spring Kit, AR-15, 5.5 oz

The Kak Industry K-SPEC Buffer and Spring Kit (brand part no. 522-0704-108) pairs a 5.5-ounce K-SPEC buffer with a matched spring, engineered specifically to reduce felt recoil and deliver faster follow-up shots on an AR-15. KAK developed the K-SPEC system by drawing on recoil management ideas that have already proven out in pistol operating systems, where many designs have moved from a single-piece recoil rod assembly to a dual recoil rod with a compression guide rod. Applying that same philosophy to an AR-15 buffer and spring pairing gives shooters a smoother recoil impulse without swapping the buffer tube or receiver extension. It is sold as a matched kit, so the buffer weight and spring rate are tuned to work together rather than requiring separate trial and error.
