Things You'll Need
Instructions
Remove the magazine. Retract the bolt and ensure the chamber is clear of live ammunition.
Use the Dremel Tool with a cutoff wheel attachment to grind away the spot-weld on the nut at the end of the muzzle. The spot weld is usually on the underside of the barrel. Do not cut too far and nick the threads.
Use the flat-blade screwdriver to depress the spring-loaded pin that locks into the detent on the barrel nut.
Use the pliers to unscrew the barrel nut. The threads are left-hand thread, so turn the nut clockwise to unscrew it.
Replace the barrel nut with an approved flash hider.
