Spikes Heavy Buffer ST-T3 Multi-Caliber Black Anodized Aluminum/Tungsten AR-Platform

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.
