I clean this rifle once each 2000-3000 rounds, most of which are dirty-ass Russian ammo. Other than the inherent accuracy issues of inconsistent crap import ammo, I haven't had any heartburn. I don't think I've ever actually had a stoppage, except for a feeding issue with a dented black-follower magazine that got hammer therapy.
I think most of the "ARs are finicky or unreliable" folklore comes from people who thought that their Bushmaster/DPMS/whatever was "Just as good as" a Colt/BCM/DD, When it turns out that their rifle sucks, they assume that the good rifles must also suck.
(And it's probably not a true recce, since it's got a 1:7 CL 5.56 barrel instead of a 1:8 stainless Wylde.)
