I’ve got a (15-20 yrs) old Armalite AR 10 that works, can is Omega, the gas block is simple with a plate that has 3 holes you tune then just push left or right, the name has slipped my mind tho
My brother witnessed (migrants) being off loaded from planes, loaded into buses at the Lafayette FedEx/UPS terminals, when I run at night they have bus loads of (M’s) filling up the truck stops, strange!
