2A Armament .750 Internal Bore Gas Block

All the same great styling of our 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.
