The 2A ARMAMENT Steel Gas Block has all the same great styling of 2A's popular titanium gas blocks but in black oxide finished steel. The low profile design works well under hand guards, and anywhere else that space is at a premium. A basic two set screw design ensures a secure fit, and an easy installation. Blue locking compound is recommended.
