The PM-84 Glauberyt or FB Glauberyt is a Polish Submachine Gun, adopted in 1984. Unlike the earlier PM-63 RAK, it utilizes an internal closed bolt mechanism instead of external reciprocating slide. The Weapon features handgun-like ergonomics, foldable Vertical Foregrip, retractable stock, vertical charging handle knob and sheet metal rounded trigger guard.
This tag applies to any PM-84 variants such as the 9mm Parabellum PM-84P, or the more modern PM-06 with mounting rail on top.
