I just completed a 1000 round test using various factory and reloads (115, 124, and 147 gn), all suppressed, without cleaning. I had one failure to feed at around the 700 round mark, which I believe was due to rearward pressure applied to the magazine while using a range bag as a rest.
Magazines used were Glock, KCI, Magpul, and ETS.
This carbine is just plain fun.
My wife really liked it as well.
I plan to use this as a dedicated truck gun, and I need 2 more.
