Interference-Fit Shotgun Muzzle Brake



We finally got the custom muzzle-brake mounted on the Mossberg 590 and got to shoot some rounds through it.   What's unique about this brake is it isn't held on by screws or welds,  etc.  It's a shrink-fit.   The brake was made a couple thousands of an inch smaller than the barrel.  The brake was heated up and it expanded and just slid over the barrel.  Once it cooled down,   it stays on tight as a drum.   We got some cool muzzle flashes blowing out the sides during some filming today.
