Overview
This firearm was a modified variation of the M/46. The only major improvement was the simplified retracting handle. Introduction of the M/50 occurred on November 7, 1950, at Mosede, Denmark, until 1953.[1]
The M/50 is made of stamped sheet metal. It is an open bolt design which means it fires when the bolt is in the locked back open position with a fixed firing pin. The M/46 and M/50 share a unique design: the firearm is stamped from two pieces of sheet metal which are shaped with an integral rear pistol grip and magazine housing. The two pieces fit together like a clam shell with the hinge at the rear of the pistol grip. The firearm is held together with a barrel locking nut which is threaded onto the fore section of the two receiver halves. The pistol grip is hollow, providing storage space for a magazine loading tool.[1]
The folding stock is made of tubular steel covered with leather and folds onto the right side of the firearm. The M/50 fires in full-auto only. It also features a safety lever (also known as grip safety), unusually placed in front of the forward magazine housing. To fire the M/50 the operator must grip the magazine housing and hold down the safety lever.[2]
