PM-63 Rak – Polish submachine gun powered by a 9 × 18 mm Makarov cartridge.
The submachine gun is equipped with a metal folding stock, sliding to the rear, with a foldable buttstock. There is a fold-out front grip at the front. Shooting with the stock extended is a lot of fun – three points of support ensure high stability of the weapon. Very light construction.
The spoon in the front part causes the gun to have practically no recoil.
