This is a 1954 Chinese type 53 (a clone of the Soviet M44 Mosin carbine). Somebody chopped the forend short, replaced the buttstock with an AKMS folding stock and a pistol grip of unknown provenance.
The end result is a rifle that’s nearly useless for bayonet fighting for lack of a grip space for the support hand, and rather unpleasant to fire thanks to the underfolding stock. That stock, already uncomfortable on the lower-powered, self-loading AKMS, was originally meant for an open bolt 9mm submachine gun (MP38/40) with almost no felt recoil. Every round fired from this bolt action is outright painful.
