Detailing the development and operational history of the RG-6 (6G39) 40mm Six-Shot Grenade Launcher.  Entry last updated on 7/11/2017. Authored by Staff Writer. Content ©
With the growing need to fight more urban environment battles, the Russian military adopted the capable, 40mm multi-shot "RG-6" grenade launcher (GRAU designation of "6G30") in 1994. The weapon has since seen issue to Ministry of Internal Affairs elements as well with combat action centering on both Chechen Wars and current, on-going military operations in the south of Russia. Design of the weapon is attributed to TsKIB SOO and production is ongoing as of this writing (February 2014).

At its core, the RG-6 is a semi-automatic weapon chambered for the special caseless 40mm VOG-25 series grenade - the same as featured in the standard-issue GL-25 underslung assault rifle launcher (detailed elsewhere on this site). The RG-6 sports a Double-Action Only (DAO) trigger set with enlarged loop to support a gloved hand and can sustain a rate-of-fire up to 18 rounds per minute. Grenades are housed in a six-shot rotating cylinder which swings out for reloading. Unlike Western repeat-fire grenade launchers (which load through the breech end) , the RG-6 is loaded through the muzzle end of the cylinder chambers. A spring used to rotate the cylinder is then manually wound prior to firing. Another unique facet of the cylinder's design is that each chamber is rifled and the barrel left as smoothbore. Thusly, the chambers themselves impart the necessary rotation upon the exiting projectile (as opposed to the barrel).

Despite its size, the unit's weight is a manageable 13.5lbs. The operator supports the weapon through a traditional pistol grip aft of the cylinder and a vertical foregrip forward of the cylinder with a telescoping stock (padded) held to the shoulder. The stock collapses into the tubular frame seen above the cylinder. The weapon fires a grenade at a muzzle velocity of 250 feet per second out to a range of 1,300 feet. Sighting is through a collapsible ladder-type assembly. Other features include a manual safety and several built-in mechanisms to prevent accidental discharge.

As can be expected with a weapon of this type, it can fire various ammunition types - from High-Explosive (HE), FRAGmentation (FRAG) and smoke to less-than-lethal rounds for crowd control (CS Gas and Baton). Grenades are fuse-armed with explosive warheads and integrated propellant supplies while weighing a little over 1lb.
