So, got it the other day and I'm pretty pleased so far. Wasn't caked in grease, just well lubed with appropriate lubricant. Metalwork was cleaner and less haphazard than I was expecting and everything feels smooth.
I stripped it down and put it back together to check on it, loaded some 5 and 10 round mags with cheap birdshot and will go break it in as soon as I can, but I'm short of places to shoot right now.
The knockoff magpul folding irons are probably the worst part of it and they actually are better than most of the cheap copies I've seen. I'll be going with a red dot once I've broken it in a bit.
Overall I'm pleasantly surprised, but then again I haven't shot it yet lol
