TacFire MAR001S2 AR-15 Low-Profile Micro Gas Block .750" - Black Oxide Steel

The TacFire MAR001S2 is a low-profile micro gas block purpose-built for AR-15 platforms that use a .750" diameter gas journal. CNC precision machined from quality steel and heat treated for service life, the block carries an erosion-resistant black oxide finish that holds up to sustained fire and field handling. Its super-compact footprint keeps the top of the barrel clean for optics mounting and clears most free-float handguards without interference.

Designed as a direct replacement, this micro block fits any AR-pattern barrel with a .750" gas journal, making it a versatile choice for custom builds and repairs. A roll pin and set screws are included for secure installation, and the lightweight steel construction keeps overall rifle weight to a minimum.
