Taking a page from other's military playbook, the nation of Poland designed, developed and adopted an indigenous, portable multi-shot grenade-launching weapon in the Granatnik RGP-40 by OBR SM Tarnow. The weapon system follows closely the lines well-established by the South African Milkor MGL line and includes a six-shot, rotating cylinder magazine capable of firing various 40x46mm SR grenades. The pistol grip is integrated as is an adjustable shoulder stock. A foregrip under the 9.8" long barrel provides frontal support. Picatinny rail sections over the receiver and along the barrel shroud allow for a series of optics and tactical accessories to be fitted. Firing is through a semi-automatic action. The RGP-40 was unveiled during 2008 at the International Defence Exhibition in Kielce. In its current form, the RGP-40 remains an in-progress weapon system with its first potential military operator possibly becoming the Polish Army.

The RGP-40 features a rotating drum magazine cylinder of 140mm length. Its length allows it to take various ammunition types in the lethal and non-lethal range. As such, the weapon can be used across military and police operations with equal success. Its portability requires just a single operator and the semi-automatic action provides quick reaction, the operator able to loose the munitions load in seconds for successive firing maneuvers. The drum manages up to six grenade casings with the chambers lining up directly with the receiver rear and the barrel at front. The shoulder stock sits just slightly above this line as a third position of support when firing.

It is known that the RGP-40 design was revised some during 2010.©MilitaryFactory.com
