Tacfire AR-15 Heavy Buffer 3 oz

The Tacfire AR-15 Heavy Buffer 3 oz is a mil-spec weight replacement buffer designed for shooters and operators who demand precision control over bolt carrier group velocity and recoil impulse. Built for both tactical and competitive applications, this heavy buffer addresses cycling issues in heavy or suppressed AR-15 builds where standard buffers allow excessive carrier velocity.

At 3 ounces, the Tacfire AR-15 Heavy Buffer substantially increases reciprocating mass within your buffer tube, which slows bolt carrier group acceleration and reduces peak recoil force transmitted to your shoulder and sight picture. This design principle is critical in suppressed configurations where reduced back-pressure would otherwise cause the carrier to cycle too fast, inducing short-stroking and reliability failures.

This heavy buffer is ideal for law enforcement and military personnel running suppressed duty rifles, precision long-range builds, or specialized piston-driven platforms where carrier velocity management directly impacts weapon reliability. Installation is straightforward—simply swap your existing buffer for the Tacfire buffer without the need for tools.
