"Gyrojets are a family of unique firearms named for the method of gyroscopically stabilizing its projectiles. Firing small rockets rather than inert bullets, they have little recoil and doesn't require a heavy barrel to resist the pressure of the combustion gases. Velocity on leaving the tube is very low, but increases to around 400 m/s at 9 meters. The result is a very lightweight weapon with excellent ballistics. Gyrojets come in pistol, carbine, rifle and machine-gun versions."@en . "55"^^ . "Gyrojet pistol"@en . .

Velocity on leaving the tube was very low, but increased to around 1250fps at 30ft. The result was a very lightweight weapon with excellent ballistics. Long out of production, today they are a coveted collector's item with prices for even the most common model ranging above $1,000. They are, however, rarely fired; ammunition, when available at all, can cost over $100 per round."@en . .
