I own a 15" Encore barrel in 454 Casull. I shoot mostly 45 Colt rounds as the recoil bloodies my middle finger on the trigger guard when firing full power Casull loads. I've been thinking about having the barrel threaded and installing a brake, then fitting this in a rifle stock for an "In the truck gun" Would the extra length of the brake make this a legal rifle? Would the brake need to be tack welded on or would just screwed on be okay? I don't want to go the SBR route. If I can't get a machinist friend interested might be an expensive fix anyway. Thoughts?
