Solid product, mine showed up with damaged threads � - Armaspec Rifter .223/5.56 Linear Muzzle Brake

I have yet to use this Ritter muzzle device as it just showed up at my front door, unit is black coated, shipping was fairly fast, only issue is my unit came with 4 moderately damaged threads on the exterior male threads of the muzzle break, blast shield would not thread over them so I used a new razor to shave the flared metal and some gun oil and forcefully screwed on the blast shield repeatedly to wear in the damaged threads.. Cut out milling on the muzzle break looks awesome and is robust, blast shield is constructed from thinner material not too impressed by that, but fastens very tight to the muzzle break when threaded on, I expect it to redirect gasses extremly well with its milled diamond crossed design.. break is bored tight for 556/223. Only reason for 3 stars is bcuz the advertised new item showed up clearly damaged
