My hubby designed and built this for R&D on one of our projects. I tease him by calling it his “space gun”. It’s inexpensive to shoot and way fun too. It’s an integrally suppressed, open bolt, 22lr machine gun that utilizes 10/22 mags.
One of my favorite and most used toys. The Solution suppressor, one suppressor with one tax stamp ($200 one time) covers me on any rifle application from my 30cal to my 22lr.
