TacFire MAR043 AR-15 Buffer - Black Anodized Aluminum$8.23
Availability: In Stock
A heavy buffer for pistol length AR-15 and M4 platforms, the TacFire Heavy Buffer is engineered to manage recoil impulse in short-stroke builds where standard buffers fall short. Pistol-length gas tubes cycle faster and with sharper momentum than carbine or rifle lengths, making buffer selection critical to reliable function and shooter comfort. This black anodized aluminum buffer weighs 4.9 ounces—comparable to an H2 buffer—and is filled with high-quality steel and machined to tight tolerances to absorb and distribute that energy without wearing your tube or inducing bolt bounce.
Recoil management matters whether you're tuning a pistol AR for suppressed subsonic loads, running a compact home-defense rifle, or dialing in a lightweight 300 Blackout. A properly weighted buffer smooths the firing cycle, reduces wear on internal components, and helps you stay on target between shots. The TacFire Heavy Buffer is a straightforward, no-frills upgrade for shooters building or refining a pistol-length platform and looking for a durable, cost-effective solution.
Drop it into your existing buffer tube—no special installation or gunsmithing required—and let the weight do the work. Black anodized finish matches most modern rifle aesthetics and resists corrosion in field conditions.
| Weight | 4.9 oz |
| Material | Anodized aluminum (body), steel (filler) |
| Finish | Black anodized |
| Platform | Pistol length AR-15/M4 |
| Buffer Tube Compatibility | Standard pistol-length tubes |
Yes. The TacFire Heavy Buffer is designed specifically for pistol-length AR-15 and M4 style rifles and uses a standard pistol-length buffer tube, so installation is straightforward.
A heavier buffer slows bolt velocity and spreads recoil impulse over a longer dwell time, which typically results in less perceived recoil and smoother cycling. At 4.9 ounces, this buffer is comparable to an H2, making it suitable for managing the sharper recoil impulse of pistol-length gas tubes.
No. The TacFire Heavy Buffer is machined and engineered to work safely within your existing buffer tube without causing wear or damage during normal use.
This buffer is for pistol-length AR platforms. Ensure your rifle is configured with a pistol-length gas tube and receiver extension before installation.
