[QUOTE="Gregg C, post: 2516145, member: 103471"] Howdy, all. I finally bit the Bullitt, and got myself an AR. It's an 80%, built by a friend of mine. Near as I can tell, he did a good job. Let's assume he knows what he is doing. The issue is, it jams. I know NOTHING about gas guns, so I want to tinker with this thing, fix the problem, and in the process, learn something. On another thread, lots of GOOD information was given. Not my thread, so here we go... So far, I have polished the feed ramp. Seemed to help some, but I did not document failures previously, so I don't really know. What I DID learn was it's from the right hand column in the magazine that these "jams" occur. Some of the guys in that thread suggested adjusting the mag lips up a touch to allow the cartridge to stick up into the bolt path more. Having decided to try that next, I noticed the back end of my mag wraps around the case head. Seems to me that if I just bend the lips up, only the shoulder will come up, and I want the entire shell to come up. Am I right? So that means I need to cut the back of the mag , to free up the whole feed lip. Am I all funkered up here ?[ATTACH type="full"]361354[/ATTACH] [/QUOTE]
