Does anyone know a good shop to take my ar15? I bought it awhile back from palmetto state armory and its never been reliable. It has a lot of trouble feeding. The bullet tip hangs up on the feedramp and I usually have to pull the charging handle back a time or two and release it before it will chamber the round. The bullet gets pretty big grooves cut into it as a result. The rifle will jam up after every other round or so. Any idea how much a shop will charge to fix this?
