Frequently Asked Questions

What is in the kit? It contains a 7075-T6 aluminum mil-spec 6-position buffer tube in matte black anodized, a 17-4 stainless carbine buffer spring, a KVP Heavy stainless steel 5.4 ounce buffer, a carbine stock lock ring (castle nut) and a carbine stock end plate.

Does it include a stock? No. It is for builders who already have a stock, are building from a stripped lower, or are converting from a fixed rifle stock.

Why a heavy buffer? KVP says an H3 buffer is one of the quickest, most cost-effective ways to smooth a suppressed or big bore AR-15 carbine, with increased reliability, reduced wear, less felt recoil and reduced bolt bounce.
