I have a DPMS LR 308 with a 18" bull barrel. I was at the range today and noticed what looked like some sort of gun part lying on the bench. Long story short. It was my ejector from the bolt. I pulled the bolt assembly out and noticed the roll pin that holds the ejector in the bolt was half way out and the ejector came out. Then the ejector spring fell out when I was looking at the bolt to see what was going on. I was able to remove the roll pin by hand. WTF? I only have like twenty rounds threw the rifle so far. Got back home and I was able to push the roll pin threw the bolt with very little effort. Looked on line and the pictures for the ejector make me think I mite have a ar 15 ejector in the bolt. The ejector I have doesnt look like the one on the midwayusa web site, it looks like the ar 15 ejector. I expanded the roll pin a bit and installed it. Just so you know I'm a rookie with dpms stuff. Oh ya and this is my first semi auto rifle. Have lots hunting rifles so semi auto is new ground for me. I have installed a few triggers in my hunting rifles before so Ive done a little bit of gun smithing but not much. Anybody come across this before. Going to call DPMS in the morning. Scotty
