Griffin Armament’s premium low-profile gas block for the AR-15, the PRIMO Gas Block, is now available for lightweight profile barrels with a .625″ gas block journal. Like the previous versions of the PRIMO, this one is machined from 416R steel with a QPQ finish. It comes pre-drilled, threaded, and with all the hardware necessary to install via screws or pinning.
