I got my new three prong flash hider that has a lip around the back where the threads are that covers about half an inch of the barrel. The instructions say that a little hole on the bottom of that lip needs to be facing down. Unfortunately after I put on the crush washer and turn the flash hider on to the threading of the barrel all the way the whole is one quarter turn past where it needs to be. The end of the barrel is touching the end of the flash Hyder on the inside and I am afraid to take a ranch and turn at an additional three quarters because I am afraid it may not go any further. Should I just ream on it? Will it go another 3/4 turn when the end of the barrel has reached the end of the inside of the flash hider? Or should I get some thin washers to add with the crush washer instead?
