Finally got to pack my new AR and head to HSA. It was my first time shooting an AR that wasn't a 22. I went through 4 full mags. My goal was just to get it sighted in, somewhat. Through these 120 rounds, I had maybe 6 or 7 FTFs. All I had to do was hit the foreword assist and it fed and fired. Sometimes it would be ok after that, for a little bit. Other times they came a few in a row. I was using ZQI 62 grain, USGI pre an 30 round mags with magpul anti tilt followers. I had spray painted the mags too. That might matter. I only had my lunch hour so I didn't have too much time to experiment. Just wondering what might be the most likely candidate. New gun/lack of lubrication, ammo, crappy mags. Would it be possible I might have gotten some overspray on the inside lip of the mag, where it feeds? Otherwise, it was really a lot of fun to shoot. And I think I got it sighted pretty well. Good enough for now anyway.
