In the never ending search to reduce the cost of shooting, I just purchased an Advantage Arms conversion. Last night I took it out to the dump just to run rounds through it. Had 2 malfunctions, 1 was a bad primer. I tried twice to get it to fire with no luck. The other is in the category of unknown at this time. The trigger pull felt a little "off", but I couldn't really tell what was wrong. Anyway, the trigger released but the round did not fire and there was no indentation on the primer. I cyled the next round into the chamber and the rest of the evening was without fault. Ran about 150 rounds through it before the sun set. It has adjustable sights and seemed to be very accurate at 25 ft or so. I plan to take it to the range Thursday and run several hundred rounds through it. This time I will be using paper targets and keeping a better record of accuracy.
