The Honey Badger's stainless steel barrel features an adjustable gas block, 25 tapered muzzle, and is compatible with mil-spec AR receivers. Stainless steel Gas Block is ''infinitely'' adjustable utilizing stainless set screws. One screw to increase or restrict the flow of gas to the system, and another to lock the adjustment screw in place. The Gas Block uses an index pin to guarantee gas port alignment, and is held in place with a Gas Block Jam Nut. This alleviates the need for set screws or damaging taper pins, leaving the barrel's integrity intact.
