Kaw Valley Precision Mil-Spec 6-Position Buffer Tube Features The Kaw Valley Precision Mil-Spec 6-Position Buffer Tube is machined from 7075-T6 aluminum a high-strength alloy that holds up to the repeated impact and spring pressure of a carbine s recoil system. Built to the mil-spec dimensional standard it accepts the wide range of six-position collapsible stocks already on the market without compatibility concerns. The matte black hardcoat anodized finish resists scratches corrosion and wear through years of hard use keeping the tube looking clean long after installation. This mil-spec sizing also ensures the buffer spring and buffer weight seat correctly for reliable cycling. The kit arrives complete with a carbine stock lock ring castle nut and a carbine stock end plate giving builders every part needed to mount the tube to a mil-spec lower receiver without sourcing additional hardware. Having the castle nut and end plate included saves time and prevents mismatched parts that can cause a loose or wobbly buffer tube installation. This buffer tube is a practical foundation for anyone building a rifle or upgrading from a fixed stock to an adjustable six-position setup. For AR-platform builders who want a durable correctly sized buffer tube with all the hardware in one box Kaw Valley Precision delivers a solid no-surprises option.
