Sometimes you have to unscrew a can or other peripherals. Then they need to be screwed back on again, safe and secure.

I read online that these crush washers are one use only and I did experience that. The washers start out as a certain size but once torqued down they make a new shape and help hold the flash hider on. They worked great on my rifle and fit just right, I would note that installing once you think you got it, torque it, even more, they really need to be cranked down on to fit properly. ... show more
