Just got got one last week and put 100 rounds thru it yesterday without a hiccup. I put a Streamlight light and red laser under the barrel, and it was easy hitting body targets at 60'ft and 75'ft with quick shots, and very little recoil. Lots of fun putting 30 rds. down range real fast, but not as much fun having to reload just one mag. I can't find any other mags as of now as they are scarce as hens teeth. The MPX fits nicely concealed in a back pack. Will be getting a buffer tube attachment for cheek rest and a RDS soon. Will probably get the aluminum AFG but $50.00 bucks is a little steep. The bungee strap is real nice that comes with it, and it would allow concealed carry under a large coat such as a trench coat.
