Tacfire Mar047Pccap Mil-Spec Buffer Tube Black Matte
The TacFire Mil-Spec Buffer Tube is a straightforward, no-frills replacement or upgrade component for AR-pattern rifles and pistol-caliber carbines. Built to military specifications, this black matte buffer tube handles the mechanical side of your AR's action reliably and consistently, whether you're assembling a new build, maintaining an existing rifle, or swapping out worn hardware. It's the kind of part that doesn't get noticed when it's working—which is exactly how it should be.
Mil-Spec buffer tubes are the standard on countless working rifles across the country. If you're familiar with AR platform rifles, you already know their role: they house the buffer and spring, manage the bolt carrier group's rearward travel, and interface with your stock or brace. The TacFire version delivers that function in a durable black matte finish that resists glare and won't stand out on your rifle.
This is an ideal choice for builders, gunsmiths, and shooters who need a dependable buffer tube without paying a premium for fancy coatings or exotic finishes. It's built to work with standard AR stocks, braces, and buffer systems designed around mil-spec dimensions. Whether you're putting together a tactical rifle, a precision build, or a practical hunting setup, a quality buffer tube is foundational—and the TacFire Mil-Spec delivers.
