Russian 40mm Semi-auto Grenade Launcher

The RG-6 (GRAU designation 6G30) is a Russian 40 mm semi-automatic, 6-shot grenade launcher developed between 1993 and 1994 by TSKIB SOO. RG-6 is designed to fire all standard 40mm "caseless" grenades, available for the general issue GP-25 underbarrel launcher. The design of the RG-6 is, apparently, heavily influenced by the South African Milkor MGL grenade launcher, with some differences. The key difference is that RG-6 uses "caseless" rounds, and thus its cylinder is loaded from the front. The "barrel" is, in fact, a smoothbore tube, which served only as a support for front grip and sights. The double-action only trigger unit is also modified from GP-25, with manual safety and several automatic safeties. Learn more at
