Shooter
I haven’t had this rifle but a couple of months now I purchased it from a forum meme we who said he had it built but a local gun shop. I don’t know a lot about any of my ARs other than what I’ve read in manuals and review videos or how to videos to disassemble,oil/lubricant,clean, and to upgrade all sorts of parts. I purchased some 7.62x51 nato I believe it was sar or zar but 147grain fmj (m80) brass cased of course.I ordered somewhere around 300 rounds or so along with 200rounds of Tula Tula 147 grain fmj steel cased. The first time I fired the rifle it was actually my 3 boys and fired 3-4 each of the sar/zar. I had one failure to eject. My range trip I brought 60 rounds of Tula expecting the steel case to run worse than the brass but zero issues. Second range trip fired 80 Tula with zero issues and brought 10 rounds of the sar/zar and in between shots it wouldn’t go all the way into battery even with forward assist and not only that the charging handle wouldn’t budge. Had to carefully run cleaning rod down barrel and charge at same time to get it to budge. This happened at least 3 times in 10 rounds. So I bought some malaysia surplus ammo and loaded a mag to see if it would chamber all the way repeatedly and it seamed to but there is a v shape scratch/marring on all 20 rounds I chambered.am I doing something wrong or is there something wrong with my rifle? Please help.
