This rifle-length assembly is built around the same buffer tube length used on original M16A2-pattern rifles, so the buffer, spring, and tube dimensions match what a rifle-length gas system and rifle-length handguard setup expect; swapping in a shorter carbine buffer tube here would leave the rifle spring over-compressed. Because the stock itself doesn’t collapse or adjust, there’s no buffer tube retention detent or takedown pin to line up during install — the tube threads directly onto the lower receiver’s threaded extension and the stock body slides on before the castle nut is torqued down. This kit is sized for a standard AR-15 rifle-length lower and is not a drop-in fit for a pistol-length or carbine-length buffer tube.
