So. My boss picked this up at an estate sale and we can’t figure out WTH it is. Has a .22 magazine, and there’s a squirrel factory etched into each side of the stock. As for the protrusion where the barrel should be it’s a piece machined aluminum with a machined threaded end to screw in where the barrel should into the receiver, with the business end not having a muzzle but instead the gases vent out to either side. Thoughts?
