Kaw Valley Precision 6 Position Stock Completion Kit Features The Kaw Valley Precision 6 Position Stock Completion Kit centers on a 7075-T6 aluminum mil-spec six position buffer tube finished in matte black anodize for a durable corrosion resistant surface that matches standard AR hardware. Paired with the tube is a 17-4 stainless steel carbine buffer spring featuring a passivated finish for long service life under repeated compression. The included KVP heavy stainless steel buffer weighs 5.4 ounces a weight chosen to help manage recoil impulse and improve cycling reliability compared to a standard carbine buffer. Together these components form the core of a complete functional stock assembly. Rounding out the kit is a carbine stock lock ring also known as a castle nut along with a carbine stock end plate giving builders every part needed to mount a six position stock without sourcing pieces separately. This all in one approach saves time and ensures every component is matched for proper fit and function. Builders replacing a damaged tube or upgrading buffer weight will find this kit a convenient complete solution. This Kaw Valley Precision completion kit is available for sale at GrabAGun for AR builders and upgraders.
