Last week I bought a Stag Arms model 2L, and have been very happy with it, but I have noticed something that I thought I should ask about. I do not have a picture of it, but I can probably get one if needed. It has had approximately 240 rounds through it, thoroughly cleaned and lubricated after 100. When I was stripping it down to clean it today, I noticed that the bolt cam pin is starting to get a great deal of wear, with grooves beginning to wear in it where it contacts the bolt carrier. It sounds like kind of a noobish question, but is this normal for AR's? Thanks in advance, and I can try to get pictures if they are needed.
