Tight specs at a great value.
BCM Low Profile Gas Blocks are made of machined steel, and given a phosphate finish. When BCM makes their gas blocks, they are manufactured within very tight Mil-Spec tolerances on all ID’s. The barrel ID is then honed after finish per USGI TDP to ensure proper fitment.

Set Screws are Steel 10-32 x 3/16 Knurled Cup Point
