The Spike’s Tactical ST-T1 Heavy Tungsten Buffer (brand part no. SLA00T1) is a tungsten-filled buffer made to replace a standard carbine buffer. Spike’s machines the body from solid aluminum billet, fills it with crushed tungsten and finishes it in black anodizing. A mil-spec bumper rides on the end. It belongs to the Spike’s tungsten buffer family, which also includes the T2 and T3, and this listing is the T1. It is a simple upgrade for an AR build that calls for more buffer weight.
