I have a Remington 700 P in .308 with threaded barrel and Gemtech HVT suppressor. I don't have thread protector and plan to use a JP Enterprises muzzle brake for this when not using suppressor. When I place the brake on the barrel, there is a gap that I would imagine I need to use shims to fill. I'm sure this is basic/common sense but not to me just yet. Please advise the proper way to do/fit this.
Thanks!
