TacFire Mil-Spec Buffer Tube Features The TacFire Mil-Spec Buffer Tube is machined to mil-spec dimensions the standard most collapsible AR stocks and buffer tube accessories are designed around. Building to that spec means the tube drops into a wide range of mil-spec stocks end plates and castle nuts without the fitment issues that come with commercial-spec hardware. At 11.7 inches in length it matches the footprint builders expect when replacing a damaged or worn buffer tube or upgrading an older build. The black matte finish gives it a durable low-glare surface that blends cleanly with most AR-platform furniture. TacFire includes the buffer tube as part of a five piece set giving builders the related hardware alongside the tube itself rather than requiring separate purchases. That bundled approach simplifies a build or repair since the pieces are matched and ready to install together. A buffer tube is a foundational structural component on any AR-platform rifle or pistol so choosing one built to mil-spec tolerances helps ensure the rest of the stock system functions as intended. This TacFire buffer tube is for sale at GrabAGun for builders and armorers completing or upgrading an AR-platform project.
