The Spike’s Tactical ST-15 complete lower solves the recoil control problem by including the ST-T2 tungsten heavy buffer, which reduces felt recoil and improves cycling reliability with a wider range of ammunition. This lower works exceptionally well for shooters building their first AR-15 who want quality components pre-assembled, and for anyone adding a backup lower to their parts inventory. What sets the ST-15 apart is the tungsten heavy buffer that provides better mass distribution than steel buffers – you get smoother cycling and reduced muzzle rise without needing to upgrade components later, plus the color-filled roll marks give the lower a finished custom appearance right out of the box.
