Kaw Valley Precision Pistol Stock Completion Kit Features The Kaw Valley Precision Pistol Stock Completion Kit pairs a 7075-T6 aluminum buffer tube with a 7.5 ounce stainless steel blowback buffer sized for pistol caliber carbine applications. The heavier buffer weight helps manage the faster cycling of pistol caliber blowback actions improving reliability and reducing felt recoil at the shoulder or brace. A KVP extra power 17-4 stainless steel spring is matched to the buffer to maintain correct bolt carrier velocity and consistent lockup through the cycle. Together these parts are built specifically for pistol caliber platforms rather than borrowed from a rifle caliber setup. The buffer tube itself carries a matte black anodized finish that resists wear and matches most black builds without drawing attention. A carbine stock lock ring castle nut and a carbine stock end plate are included so the builder does not need to source these small but essential parts separately. Every component in the kit is designed to work together reducing the guesswork of mixing compatible buffer spring and tube parts from different sources. For anyone finishing a pistol caliber carbine or AR pistol build this completion kit from Kaw Valley Precision is available at GrabAGun.
