The ST-T3 buffer provides a firmer recoil impulse and
is intended for machine guns, suppressed weapons, and rifles that suffer
from overgassing. It doesn't have any fluids to leak out like some
other buffers, so it's 100% maintenance free. The ST-T3 buffer weighs in
at 154g/5.4oz and the body is CNC machined from solid billet Aluminum
bar stock for strength and durability. To finish it all off, it's
Anodized matte black and laser engraved with the Spike's Tactical Logo.
Each ST-T3 buffer contains three sliding solid weights cut from tungsten
bar stock and topped off with a Mil-Spec bumper. The ST-T3 eliminates
the chance of bolt bounce, helps with muzzle rise when firing in
full-auto, and cuts down on felt recoil. It's designed for .223/5.56 but
it works in all calibers.
