In the configuration you mention and as a Semi auto, it is a niche rifle IHMO, I see a better version of the old M7 survival rifle with accuracy potential to 100 yds, and 90 to 120 rds available, if you just pick it up and go. I doubt the accuracy for very small game like squirrels and rabbits at 100, but definitely viable for torso shots with ease at 100, if the accuracy is 2.5 MOA. The stock could also have one section to just dump live rounds up to

rounds, and only a couple of magazines, and increase the potential a little.
If they made it in full auto, we could not buy it, as it is post 1986, unless you are a class 3 dealer. Would be massive fun to play with in FA for sure.
