The Kaw Valley Precision Pistol Stock Comp Kit with 5.4 oz Buffer (Kaw Valley Precision part no. KVPPISTOLKIT54SS) bundles the receiver extension, buffer, and buffer spring needed to complete an AR15 pistol build using a stabilizing brace, saving shooters from sourcing each buffer system part separately. The included buffer weighs 5.4 ounces and is built from stainless steel, giving a slightly heavier-than-standard weight that can help smooth cycling. Pistol-length receiver extensions are shorter than a standard rifle buffer tube and typically don’t include stock adjustment positions, matching the fixed-length nature of most AR-pattern pistol braces. This is a convenient one-stop kit for finishing the rear of an AR15 pistol build.
