bad gas cylinder?

Chris good question.....I checked, and it will pass the tilt test, but only with the trigger group removed. It acts the same way with my old stock. Everytime I lock in the trigger group it binds. I thought it was the op rod rubbing against the stock but I did the tilt test on the op rod with the bolt removed and had no binding when I locked the trigger group. But when the bolt is in, the op rod is removed, and the trigger group locked in, it binds about half way closed.
