The M203 grenade launcher was developed by AAI in 1967 and was mass-produced by many companies, including Colt. In 1969, M203 was adopted by the American army. The “grenade launcher” is mounted on M16 rifles (M4) and is capable of firing 40-mm grenades at a distance of 400 m. To date, more than 250 000 M203 grenade launchers, which are in service with forty armies of the world, have been launched.

Considering that the original M203 is a military development and cannot be sold freely in the civilian market, Colt has somewhat “adapted” it. So, the version of the grenade launcher, which anyone in the US can buy, was called the Colt M203 37mm and was made in the caliber 37 mm. The shooter can use it with any non-lethal 37-mm grenade, which does not violate applicable law.
The Colt M203 37mm is not the only grenade launcher released for the US civilian market, but it is the first M203 “clone” released by the original “grenade launcher” manufacturer for the M16 / M4 rifles. In the US, the M203 37mm rocket launcher is sold at Arms Unlimited stores (a subsidiary of Colt) in two versions - with 9- and 12-inch trunks. The retail value of both versions is declared at $ 3500, while the grenade launchers were originally sold at a discount of $ 1500, reports "Warspot"
