How do I line up my muzzle brake?
Hey all. I recently bought a PTS M4SDII Airsoft Muzzle Brake - 14mm Positive for my Umarex Elite T.A.R. 21, and cannot for the life of me get the dang thing to line up right. I've bought two sets of washers and neither set works. I'm hoping to get some tips before spending any more money. Thanks!
