JK-47 33 Posted December 29, 2007 Report Share Posted December 29, 2007 My .223 has a raised "ring" on the bolt face arround the firing pin hole. It seems to be designed to be just a bit larger than the primer, its presence there on the bolt face results in a "crimp" around the primer of fired brass. the topic is touched on briefly here. Is there any harm in removing this ring? I believe I read elsewhere that it is annother Russian gun control measure, that they don't want Russian citizzens reloading so the gov't can keep better track of ammunition; hence the annoying crimp arround the primer pocket. So here in the USA, is there any reason not to remove that feature? could I chuck a dremel sized grinding stone in the drill press and remove it ? Quote Link to post Share on other sites
