What are you thoughts on using Barrel Vice Jaws for muzzle device installations? I see some people use them, and then others that don't... I don't have the experience to really know yet. Found this one: http://www.brownells.com/gunsmith-t...m16-accu-grip-barrel-vise-jaws-prod12799.aspx It makes sense to me that it would reduce the force placed on the upper receive and barrel nut which from the tip of the barrel could be excessive if someone wasn't paying attention while torquing a brake on. Thank you for any input.
