MP22A2 prototype

In "Home Workshop Volume 3" by Bill Holmes, I adapted a weapon featuring a square tube upper receiver. It also has a custom trigger mechanism and a two-part lower receiver. The caliber is .22LR with an open bolt, semi- and full-auto capabilities (though the latter is incomplete). To enhance the design, I created a false magazine for rendering and 3D fitting based on a .22 AK47. Despite needing some screws and pins, the weapon is fully functional except for its full-auto feature.
