The Q LLC Adjustable Gas Block, .750-inch, Silver Steel (brand part number GB-ADJ) gives AR-platform shooters full control over their rifle’s gas system. Machined by Q LLC from stainless steel, it uses the same infinitely adjustable design found on the Honey Badger, with one set screw to increase or restrict gas flow and a second to lock that setting in place. Fitting a .750-inch barrel journal, it lets shooters dial in reliable cycling whether they are running a suppressor, subsonic ammunition, or a lightweight buffer setup that needs less gas pressure than stock.
