No, this is not a Glock post.
I just have to rave for a minute. I have a CMMG drop-in 22 conversion bolt, that has been just incredibly reliable. I'm totally amazed by it. I've been shooting it in a weekly league for going on two years now. 50-75 rounds per week. Every week. I don't think I have cleaned it in...I can't even remember. A year? It's completely filthy. At least a thousand rounds with not one single malfunction of any kind. Weather from 70˚ and rain to 0˚F, and everything in between. I've always run the cheap Federal 36 grain copper plated ammo (per CMMG recommendation.) I probably just jinxed myself, but...1k rounds in a rimfire with no malfunctions?
On a related note, I also run a Beretta 92 in that same league, and haven't cleaned that gun either. At least 1k rounds without a single malfunction. (115 grn Ball ammo.) Again, hope I didn't just jinx myself.
What guns have you owned that far exceeded your expectations for reliability + low/no maintenance?
