Just ordered one of each (rifle and the muzzle brake ). I love to shoot but I'm by no means a gunsmith or an armorer. Anybody here have experience installing a muzzle break on one of these babies? I don't know if their as easy as switching out an M4 muzzle break/flash hider. Gunsmithing required or is this a good 'ol DIY that'll take 10 min out of my day? Would love to hear some thoughts and advice.
