Lol. My memory on AR’s is very spotty. For instance, just this last few days I decided to get out an AR 9mm build I had stuffed away in frustration, as I recall. Hahn adapter block for colt mags, I think a Cmmg upper. I can’t remember the lpk, but it has a heavy buffer which I tweaked for rearward travel so the bolt would travel far enough back. I remember the feed shoving rounds high above the chamber and jamming, I thought. Now I remember, the bolt was short stroking and not picking up rounds.
Anyways, somewhere around here I misplaced a 32 round mag the other day, still haven’t found it. Pulled out another and fed some snap caps through the action, works like a charm. Feeds, ejects, hold open works, etc.
so much for memory. The work on the buffer had fixed it.
But wait there’s more! Was looking at buying a few more mags, I did order 2 last week, and they came today. This made 3 total, and one missing. All three are feeding fine too. My initial intent was to check mag insertion height to see if it was causing the feed problem, but there is no problem. Yay. Well, while searching for the missing mag up in the boxes of magazines upstairs, I decided to look at the AR15 5.56 mags. Lo and behold, 5 more 32 round 9mm mags were hiding with the 5.56 mags. But still one missing. It will turn up. But now I know I don’t need more mags. Lol.
