Need help installing an AR flash hider in South Bend/NWI

[PTinbound]

Hey all, I'm embarrassed to admit but I had switched out the flash hiders on an upper but then changed my mind. Now I can't get the stinking original back on without it being upside down. I've watched YouTube videos and I know it can't be that hard but I just can't get it to work. I live just NW of South Bend but I go back to NWI frequently. Would any of you AR gurus out there be willing to help me out at the place of your choosing?

Did you use a new crush washer? They collapse as they are tightened and should be replaced when changing muzzle devices.

What they said! If you need a hand I am in South Bend. PM me. But you will need a new washer first.
