Description
The BCM LGB625 Low Profile Gas Block is built by Bravo Company Manufacturing to deliver a clean, snag-free fit on .625″ diameter AR-15/M16/M4 barrels. Machined from steel and finished in durable Black Phosphate, this gas block is manufactured within very tight Mil-Spec tolerances for a precise, repeatable lockup on the barrel journal.
The low-profile silhouette keeps the sight picture over the handguard free of bulk, making it a strong choice for free-float handguard setups, modern red-dot rifles, and any build where the shooter wants a tight gas block profile without giving up the rigidity of a properly torqued steel component. The internal diameter is honed to seat squarely on the barrel, and the block is secured with knurled cup-point set screws for a gas-tight fit under hard use.
