The American 180

This is the only full auto weapon I've ever fired (department owned) except for a malfunctioning model 60 which I fixed.
That 180 was a hoot, the rate of fire was so high that it was almost a hum rather than a pop pop pop. It was so controllable cutting down a small tree was easy.  Wikipedia says 177 round capacity but my memory tells me it was more like 350 rounds. It took a long time t o load the magazine. If I screwed up loading the mag it would spit them out and I had to start over.
If I won a big lottery I'd buy one.

If anyone is interested in my malfunctioning glenfield model 60 story, I was at the bench sighting it in for the first time. I pulled the trigger and got a brrt. I asked the other guys if they heard that and nobody noticed it. Ok, maybe my imagination. I pulled the trigger again and brrrrrt, emptying the magazine. Nope not my imagination. I took it home and disassembled it. It was brand new but evidently sat in the rack a few years and the grease had solidified on the sear. A little cleaning cured that problem.

Back then 22lr was pretty cheap and available.

Back in the day the Marines let the junior shooters have a "range day". It was a recruiting tool for them, we were already good shooters so letting us play with the toys was their attempt to set the hook. We got to play with all the machine guns they had in their "library". It was an eye opening experience. Of course the M14 was fun but completely uncontrollable in full auto. Even the one with the heavy barrel and pistol grip stock was just too light to keep rounds on target. But the coolest one was the MG42. Technically an MG3 as it was in 7.62 but man that thing was fast shooting and controllable. Recoil was negligible and short bursts often had all the shots "on the paper".

The last full auto I shot was a .300BO AR. It was a hoot. But a full auto .22 would be a neat toy.
