The RGP-40 (Ręczny Granatnik Powtarzalny 40 mm - 40mm Handheld Repeating Grenade launcher) is Polish six-shot revolver-type 40mm grenade launcher designed by

M32 MGL

.

History

The first prototype was created in 2008 and was revealed during the

M32 MGL

variant. Its final mass production design may be different from the proposed prototype. It is planned to replace the stock with a grenade launcher-specific proprietary telescoping stock, among some other things used in the prototype to improve ergonomics and functionality.

According to plans, the main recipient of RGP-40 would be the

Police, Prison Service and other Law Enforcement forces that need weapons with high firepower capable of firing tear gas and non-lethal ammunition.^[1]

Polish Army ordered 200 RGP-40 in 2016, but eventually refused to accept manufactured grenade launchers, considering them as not meeting Army requirements.

During

2021–2022 Russo-Ukrainian crisis, in early 2022 a batch of stored RGP-40 was given by Polish government to Ukraine, and then used by Ukrainian Ground Forces.^[3]

Design

The RGP-40 is a shoulder-fired 40 mm grenade launcher with a six-round spring-driven

40×46mm grenades

. The spring-driven cylinder rotates automatically 60° while firing, but it must be wound back up after every reloading.

The main element of the weapon is the frame to which a revolver-style magazine is attached. While shooting the drum is rotated 60 degrees by the springs wounded back up when loading the cartridges into weapon.

The magazine is capable of holding 6 rounds. Chamber of cartridge has a length of 140mm, which allows the user to use both combat ammunition and special longer cartridges.

Before loading cartridges, the magazine must be rotated to left or right (Magazine is of Swing-out type cylinder type).

RGP-40 uses a double-action trigger. To prevent accidental engagement and firing, there is an ambidextrous safety selector at the top of pistol grip.

RGP-40 is equipped with a

telescopic buttstock that can be rotated vertically for better weapon handling.^[1]
