TacFire AR-15 Mil Spec Buffer Tube Kit Features The TacFire AR-15 Mil Spec Buffer Tube Kit bundles everything needed to complete a collapsible stock setup on an AR-15 or M4 pattern rifle. At its core is a Mil-Spec dimension 6-position buffer tube machined to the same diameter and spec as factory military tubes so it accepts standard AR-15 stocks and accessories without fitment issues. A carbine length buffer spring and a 3 oz buffer are included to properly cycle the action while the regular end plate and castle nut secure the tube to the receiver extension threads. Built from a combination of steel aluminum and polymer components with an anodized finish the kit is designed to resist wear through repeated adjustment and use. Rounding out the kit is a 6-position stock fitted with a QD sling swivel socket and a rubberized butt pad giving the shooter both quick sling attachment and a comfortable non-slip cheek weld at the shoulder. The QD socket accepts standard quick-detach sling mounts letting the rifle transition between sling setups without additional hardware. Made in the USA and backed by a manufacturer limited lifetime warranty this kit is built for shooters who want a dependable drop-in replacement rather than piecing together individual stock components. Whether replacing a worn factory stock or completing a new build the TacFire AR-15 Mil Spec Buffer Tube Kit delivers a complete Mil-Spec correct stock system in one box.
