Made by Señor Osorio in Nicaragua, this is a .22 rimfire caliber machine pistol with several clever design elements. It fires from an open bolt, using a .22-round Italian magazine of indeterminate origin. It has a selective trigger, with the top firing in full automatic (sliding rearward) and the bottom firing in semiauto only (pivoting). Aside from some sharp edges on the vz61-like folding stock, it is a remarkably well built and refined little pistol! http://www.patreon.com/ForgottenWeapons Cool Forgotten Weapons merch! http://shop.bbtv.com/collections/forgotten-weapons Contact: Forgotten Weapons 6281 N.
