Your DPMS is fine. Is the theoretical reliability less than a gun that has had the testing of every important part to mil-spec or higher standards. Maybe. But has anyone ever documented widespread failures of DPMS products? Not "Instructor X at school Y told my buddy...", but actual observed failures, preferably with some evidence. Not that I've ever seen (and I've seen lots of different gun's Ka-booms documented on the internet). And DPMS started as a parts supplier to the US military, then started making complete guns, which were THE ones to have during the early years of the multi-gun competitions. And those guys RAN those guns, both in practice and competitions.
And yes, I own a DPMS (among others), bought it before the AWB ban to give you an idea of its age. I've run it in the snow in the midwest, in the god-awful humidity in South Florida and the high heat and dust of Arizona. The only problems I've had are cheap ammo related and the fact I don't clean until I get a malfunction from carbon build up.
My observation is that more guns (and cars) are screwed up by people "upgrading" them when they work just fine.
The brand pissing contests are why I try to avoid AR threads.
