Product Description The TacFire AR Build Kit (Model SSRK308LPK18BN) is a Sports South Exclusive comprehensive assembly package designed for the AR-10 platform chambered in .308 Winchester. Built around an 18-inch black nitride-finished barrel with a 5/8"x24 thread pattern and a 1:10" twist rate, this kit delivers everything a builder needs to complete an AR-10 rifle - excluding only the lower receiver. From the DPMS-profile GEN.3 stripped upper receiver to the Mil-Spec M4 style 6-position adjustable stock, every component is selected for quality and compatibility. The included 15-inch slim M-LOK handguard provides ample rail space for accessories, while the DPMS-profile bolt carrier group ensures reliable semi-automatic operation. Whether you are building your first AR-10 or adding to your collection, this kit streamlines the process with a well-matched set of components.
