I want to suppress my 450BM. Just looking to make it hearing safe. I know the suppressor is going to be big. I have an approved form one, a 12" Ti tube. and plan on doing the D cell freeze plug thing (I've built 30 cal and 22 suppressors this way already).
When I'm not running suppressed I want to add a break and tame my rifle just a bit... got a wife and a little girl who may shoot it... So I got the manufacturer (SD Tactical Arms) of the tube and suppressor mount to make a muzzle break in 11/16x24 (the factory thread for 450BM's by Bushmaster). http://sdtacticalarms.com/SDTA-Muzzle-Break_p_65.html
Problem is I can't find any shims to time the break properly (its a bad idea to use crush washers on muzzle devices that mount suppressors... they can cant just a slight bit and cause baffle strikes...especially on a can long enough to tame the 450BM... ie 12").
Was thinking I'd prefer a simple jamb nut, but I cant find one thin enough... Can any one help?
