Super Gas Block - Black Oxide

Super Gas Block with Black Oxide coating - The bore of the SGB is machined to closely fit around .750” diameter mounting bosses found on most M4 Carbines and AR-15 rifles.

This is a stainless steel gas block from Geissele, and custom blackened by Potomac Armory with Black Oxide.  Very comparable to the Nitrided gas block from Geissele:  New in with factory instructions, roll pin to drill and pin, and screws to set (use one or the other) and gas block pin for tube.

Note:  Black Oxide may have small cosmetic inconsistencies.  That does not affect the coating, and the metal is stainless, so you are doubly protected.
