The Spikes Tactical SLA00T1 ST-T1 buffer is designed to deliver a robust recoil impulse suitable for machine guns, suppressed firearms, and rifles prone to overgassing. Uniquely maintenance-free with no potential for fluid leakage, as seen in other buffers, this product ensures extended durability.Weighing 85g/3oz, the ST-T1 buffer\'s body is CNC machined using solid billet Aluminum bar stock, guaranteeing strength and long-term wear resistance. An Anodized matte black finish enhances its aesthetic appeal, while the laser-engraved Spike\'s Tactical Logo further distinguishes it from other buffers.Each ST-T1 buffer includes three sliding solid weights, cut from high-grade tungsten bar stock and equipped with a Mil-Spec bumper. This design eradicates the possibility of bolt bounce and aids with muzzle rise in full-auto firing, while also reducing felt recoil effectively.Although engineered initially for .223/5.56 calibers, the ST-T1 buffer is versatile, working well with all caliber types.
