Ok I was very lazy and dumb last time I went shooting. It has only been about a week since the last time I went out but I just tonite got aorund to cleaning my AR. I think by the looks of my bolt I may not have been doing a great job in the past but I never nitced any build up befor. I was shooting prvi and there was red shit everything from the primers inside the carrier. I got most of everything cleaned and lubed but am not happy. I found this http://www.ar15.com/content/page.html?id=533 but not sure how great that is for the gun. Any suggestions or opinions of this method? I think i have heard people talk about break cleaner or soemhting befor but want experienced advice. Thank you in advance.
