Seems just about everyone has built one of these so figured I would too. While somewhat limited, it's still a viable weapon especially as an emergency back up. Several can be built disassembled and stored sealed in large pvc pipe and buried. You just never know! This one is roughed out, still need to fab the firing pin and buy the proper hardware to finish it out. Has currently a 24" barrel. Wanted a bit closer pattern than the usual 18". Had a bunch ofleft over AR stuff to use on the build. It's quite comfortable to hold/aim/fire. Thinking cut shells of low recoil ammo will work in it.
