@500ish rounds through mine, mostly surprised, several types/brands of ammo, zero issues.
About to put another few hundred down range tonight to test what I like best for subsonic.
When I had an early release prodigy, jam o matic and issues. Sent it in, if I recall, it was back in my hands in under 10 days and a perfect runner since, even in the posession of someone else (sold to friend).
Surprised it’s taken this long, to be honest, but it’ll be right when you get it back.
Only problem I’ve heard of is dirty mags causing malfunctions.
I just recently cleaned mine….because I detail stripped and cleaned the whole thing, total break down of the upper, piece by piece. Even though the mags were carboned up a bit, expected running with a can, zero malfunctions.
