Aero M5E1 Feed Issues

[DireWolf]

What would I be checking, tightness? I don't have an adjustable gas block....maybe a worthwhile mod? So nobody seemed horrified by the feed ramps. They're as expected?

Check the gas block refers in this case to making sure it didn't rotate or move (so as to no longer be properly aligned with the port on barrel). Worth checking.

Also, (failure description is a bit vague, so possible this may not be relevant) check to make sure your firing pin isn't bent and the bolt freely cams in the carrier, and that you're getting good contact between gas tube and gas key...

ETA: from what I can see in pic, would guess that your feed ramps are likely unrelated to the stated failure mode...
