BCM Low Profile Gas Block with Set Screws, .750″
The Bravo Company Manufacturing Low Profile Gas Block is manufactured within very tight MIL-SPEC tolerances.
Machined from steel then phosphate finished, the internal diameter is then honed, ensuring a correct fit to your barrel. Secured using the two provided steel 10-32 x 3/16 knurled cup point set screws.

Great gas block was the tightest fit on my barrel but won’t have to worry about it leaking gas
