Helps Control Felt Recoil & Bolt Bounce
Machined aluminum recoil buffer comes in three weights, so you can select the buffer that gives the best combination of recoil control and reliability in your carbine with an M4-type adjustable stock. All have a mil-spec polyurethane bumper, durable hard-anodized finish, and the Spike’s logo. ST-T1 is a standard-weight (3 oz.) buffer filled with low-density tungsten powder (LDTP) that eliminates the noise and shock caused by the hard reciprocating weights found in the original-style factory buffer. Aids in smoother cycling and helps minimize bolt bounce. ST-T2 is filled with high-density tungsten powder (HDTP) for extra weight (4.1 oz.) behind the carrier to reduce cycle rate. Help you stay on target in rapid-fire semi-auto operation and improves controllability in full-auto. ST-T3 gives the most aggressive reduction of felt recoil and bolt bounce with ultra-dense tungsten bar stock weights inside (5.4 oz.) for maximum recoil control in full-auto mode, suppressed weapons, or rifles that suffer from overgassing.
