Day 1: So I loaded up a bunch of different types of Scorpion Evo mags and went to the range with the evo version of the upper combo. The manticore arms mags would never fire more than 1 round before jamming, sometimes wouldn't even do the 1 round. The Magpul EV-50 mags were the same. As you can see in the video, I was able to get more rounds off with the Palmetto State Armory AK-V scorpion mags although they jammed a good amount as well. When I got home I took off the mag piece and compared it to the Glock mag lower which I haven't tried yet. My best guess is that the bit of flash on the metal feed ramp insert (that's roll pinned into the large plastic magwell upper insert) is causing the rounds to drag. I noticed that some of the rounds on the ground had some brass gouged out of them, and now seeing this burr in the feed ramp makes sense. Gonna try the Glock mag one tomorrow.
Day 2: So I went back to the range with a bunch of Glock oem 33 rounders and as you can see in the second video, everything worked great and I had a blast. Then I literally had a blast. The next mag which I didn't get on video got a few rounds into the magazine and then had an out of battery detonation which blew up the plastic parts of the Versa upper. This is my 4th Lage upper and I've never had these kinds of issues with their other parts or uppers.
edit: In case anyone asks, It's PMC factory 9mm 147gr fmj round nose. It's been running great in my other guns and other Lage uppers.
