Worse Than It Looks - Stoehr Machine Pistol (1970s) ( lemmy.world )
You might be thinking how could this bullpup pan-fed automatic pistol possibly be worse. It is also a blow forward design. Meaning the barrel physically moves forward to operate the gun each shot. This significantly increases recoil, and in theory decreases accuracy.

From what I've read it's chambered in .22 Magnum. Not a lot is written about this prototype. Presumably after making one better judgement finally caught up with its inventor.

It has sights. I don't know how you are supposed to use them. Maybe you're supposed to hold your arm straight out and shoot it like that.
Its pan magazine is held together with a hose clamp. Arguably the best feature on this gun is it takes standard AR-15 grips.

This video might be of a replica based on their others but it demonstrates some of the mechanics. Any Japanese speakers willing to help me know what exactly is going on there would be appreciated.
