The Spikes Tactical SLA00T3 Heavy Buffer ST-T3 is a multi-caliber AR-Platform buffer engineered to deliver a firmer recoil impulse for machine guns, suppressed weapons, and rifles that suffer from overgassing, while remaining maintenance-free with no fluids to leak. Laser engraved with the Spike's Tactical Logo, the ST-T3 features three sliding solid weights cut from tungsten bar stock, topped off with a Mil-Spec bumper, and designed to eliminate bolt bounce, reduce muzzle rise during full-auto fire, and cut down on felt recoil. Built around a durable aluminum/tungsten construction with a black hardcoat anodized finish, this buffer is optimized for .223/5.56 but is versatile enough to operate effectively across calibers, providing enhanced reliability and smoother operation in demanding shooting scenarios. Its integrated design and multi-caliber compatibility make it a practical upgrade for AR-Platform rifles facing overgassed cycles, offering improved control without sacrificing simplicity or maintenance. Whether youre refining a suppression setup, pushing a machine-gun-grade handling, or optimizing general AR performance, the ST-T3 from Spikes Tactical delivers a decisive recoil impulse and steadier follow-up shots with a rugged, ready-for-duty build.
