Description
The TacFire MAR001CO is a clamp-on low-profile gas block built for AR-15/M16-pattern rifles chambered in 5.56/.223. Its .750″ inside diameter clamps directly onto a standard barrel gas block journal, making it a direct replacement for the factory A2 fixed front sight base when stepping up to a free-float handguard.
The block is CNC-machined from steel and finished in a corrosion-resistant black parkerized coating, built to handle the heat and fouling of direct-impingement cycling. Its slim low-profile footprint tucks neatly under free-float handguards and modern rail systems, leaving plenty of clearance for optics and accessories on custom builds.
The package ships with the gas block plus the hardware needed for installation: a roll pin, a screw set, and a hex wrench.
