The Q LLC adjustable gas block in the .750-inch size lets an AR-15 owner tune how the rifle runs instead of accepting whatever it does (Q part no. GB-ADJ). It is a stainless steel block that is infinitely adjustable with dual stainless set screws, the same design Q uses on the Honey Badger. Turn one screw to increase or restrict gas flow, then lock the setting with the other. It suits builders who run suppressed, run hot or soft ammunition, or want less recoil and wear.
