Gas Block Review
So i looked up Cobratac instructions online and got generic instructions from a Cobratec blog which said to turn instruction screw in to start adjusting which is backe=wards from how this block worked. I know it's a pretty straightforward procedure but instructions with it would be nice, this is my first adjustable block. Looks great on the gun and was easy to dial in.
