Heavy 5.5 oz buffer designed for 9mm pistol caliber carbines. Solid construction eliminates rattle and noise while providing optimal dwell time for reliable cycling.
The TacFire AR-15 9mm Heavy Buffer is engineered specifically for shooters running pistol caliber carbines in 9mm. This is not a compromise—it's a purpose-built component that addresses the unique demands of subsonic and standard 9mm ammunition.
Pistol caliber carbines require a longer dwell time than their rifle-caliber counterparts. The TacFire heavy buffer, at 5.5 ounces, provides the mass necessary to slow bolt carrier velocity and allow proper gas expansion. This translates to more reliable cycling, reduced wear on components, and better accuracy.
Unlike buffers with moving weights inside, the TacFire uses solid construction throughout. This eliminates the metallic rattle and noise that can plague lighter alternatives. You get a smooth, quiet operating system—whether you're at the range or in the field.
If you're building or upgrading a 9mm pistol caliber carbine, the TacFire heavy buffer is a straightforward choice that delivers results.
