So I'm cleaning down my ar just now and I'm putting back all my pieces and notice my flash hider looks a little off from where it normally is positioned. I barely touch it and the thing is really loose. How tight are these suppose to be on?? Has anyone ever had this happen?

tight enough for the crush washer to be flat. Just dont make it loose haha

It should be tightened with a wrench until it's lined up with all of the exhaust cuts facing up. There should be a crush/peel washer between the flash hider and the barrel that provides the proper torque and alignment. They make a special muzzle wrench, but in reality, you can do it with any wrench that fits the nut.

3/4 inch open end wrench.
