2A Armament Steel Gas Block


2A Armament, .625, .750, or .875 Internal Bore, Gas Block, Black, 4140 Steel

SKU: N/A Categories: ,


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.
