Took a AR-7 to the range for the first time this weekend. It was one that my father-in-law gave to me. First shot wouldn't eject. Cleared it up and repeated, same thing. A little lube and it progressively got a bit better but still wouldn't fire, eject and feed the next round. Seemed to not want to toss the empty out completely. Ejector seemed ok, tension wise but maybe a bit worn on one edge. Possible problem I know. wanted to watch the cycle so firing from the hip i tried it. same thing. tried again and it went full-auto on me for a few shots. Put it away and went back to the 10/22's. Anyone else have problems with this model? Any ideas. I'd just as soon trade it off (got offered $75 bucks) but where it was a gift from FIT, I know he'll ask about it and be irked if I sell it off.
