NRS-2

The NRS-2 (Нож Разведчика Стреляющий, "Scout Firing Knife") (official GRAU index 6P25U) is a gun hybrid with a combination of a knife blade and a built-in single-shot shooting mechanism designed to fire a 7.62×42mm SP-4 (СП-4) cartridge. The SP-4 is the same cartridge designed for the PSS silent pistol.[1]

It was manufactured by the Tula Arms Plant for Soviet Spetsnaz troops in the 1980s, and is still used as a personal weapon for modern Spetsnaz troops and special law enforcement groups. The NRS-2 is designed for the blade to either be stabbed or thrown at the enemy, or fire at the enemy using the inbuilt shooting mechanism at distances up to 25 metres.

Shooting mechanism

In order to use the inbuilt shooting mechanism, the opening lever is pressed, and the barrel rotated out of the knife handle, the cartridge is inserted into the firing chamber and the barrel is then inserted back into the handle and rotated back into place using two prongs that fit into the outer latch. The flip-up lever on the right side of the NRS-2 is then pulled to cock the internal hammer, while the safety catch located beside the barrel is turned to the "fire" position. Then the user's left hand is used to hold the underside of the grip, and the right hand held against the right side, with the right index finger being placed on the single action push-button trigger, which is located above the safety catch beside the gun barrel.[2]

NR-2 survival knife

A modified version of the NRS-2 without the shooting mechanism was also developed, designated the "NR-2", with the shooting mechanism being replaced with a container of survival equipment.

gollark: Isn't that just survivorship bias?
gollark: I mean, a fridge with a touchscreen on the front so you can browse the web is *not* very useful. A fridge which can automatically track its inventory and remind you to order new things actually might be.
gollark: It'll probably mature eventually, but still.
gollark: It's a shame, too, since all this stuff could have been extremely cool, but ended up proprietary, poorly integrated, insecure and gimmicky.
