ETA: Should mention what all I have:
Model1Sales 7.62x39 16" upper kit
Spike's Tactical Stripped Lower
C-Product's latest batch of 30 round 7.62x39 mags
1) Is it normal for the charging handle latch to not seat completely without pushing it? Mine comes really close to latching, but not quite. I have the Tactical Latch from Model1Sales...
BTW, I don't recommend this latch, it's way too big and cumbersome. I'll probably be getting a standard one soon.

It could be an optical illusion, but it does look like it's raised up about 0.25 mm or so. There was something hanging down from it when I unboxed it, but after I went one stroke through the barrel with the brush, it appeared to have went away. I couldn't find it though. So maybe it just folded up in there or something. I pulled the brush through 4 times all together, and it would get hung up (just a bit) in that area every time. But since it's still raised a little and knowing that I couldn't find the piece that was hanging down, I'm a little weary about firing it. I might go have a gunsmith take a look at it just in case. Is the gas block easy enough to take off in order to inspect it myself?
3) When I was cycling it by hand to test the mags and feed ramps, the bolt jammed twice, locking it in the forward position. I shook it and tapped it both times, but it didn't help. So I pulled pretty hard and both times it freed up. What causes that?
4) Should the bolt lock back when there is no magazine inserted?
5) Why do some of my magazines lock the bolt back when they are empty and some don't?
6) THANKS!
