1. A dirty AR15 fire 1,000 rounds without FTFs or FTEs.
Actually I see this all the time and in all the ARs I've ever owned in 20 years I only had problems with one that I got from someone else. It is fixed now and has a 0 error performance rate since coming back from Colt.
2. A AKM (7.62x39) fail.
Actually I've seen 3 different ones fail in the last year. All were Sar 1s, and a Sar 2, and one Sar 1 seemed to FTE every 6th round or so. The Sar 2 had a bolt that travelled over a fired hammer trapping it under the bolt.
3. A Special Weapons / Tactical Weapons Training Academy product work.
Actually it was not a SW / TWAT gun but the sten mag conversion for the HK USC. And it wasn't installed by SW but by a real HK Armorer. I think the fact that it was installed on a factory HK gun had a lot to do with it, but I have heard that the mag conversion for the HK SL8 is much less reliable.
4. A guy from AR15.com that can't shoot 1MOA with iron sights.
Actually I've seen a LOT of these.
5. A CAI G3 owner finally understand when he shot a real HK91.
