TacFire AR-10 6-Position Stock Kit Features The TacFire 6-Position Stock Kit bundles every component needed to add a mil-spec adjustable stock to an AR-10 build starting with the 6-position buffer tube that houses the buffer and spring assembly. A 3.4 ounce buffer paired with a carbine length buffer spring is sized specifically for the AR-10 platform s recoil impulse helping the action cycle reliably across a range of ammunition. The included M4 stock attaches to the buffer tube and adjusts across six positions letting shooters dial in length of pull to match their body size clothing layers or shooting stance. A regular end plate and castle nut complete the buffer tube installation securing the entire assembly to the lower receiver. Constructed from a combination of steel aluminum and polymer this kit balances durability where it matters most with manageable overall weight for the complete assembly. Because every component in this kit is designed to work together builders avoid the compatibility guesswork that can come from sourcing buffer tube buffer spring and stock separately from different manufacturers. The black finish matches the vast majority of AR-10 builds and components on the market keeping the overall look of the rifle consistent. For anyone building an AR-10 from a stripped lower or upgrading a fixed stock to an adjustable one this TacFire kit offers a complete straightforward path to a functional adjustable stock setup.
