Context

The standard riot gun of the South African Police Service was the 37mm Federal Riot Gun. Owing to the arms embargo imposed upon the apartheid regime, it was difficult to obtain spare parts from the USA. Due to an international arms embargo against South Africa, South Africans designed and manufactured some weapons as a small firearms industry developed locally. A South African farmer, Andries Piek, the 'accidental designer' involved with the Milkor BXP was involved with the design of this weapon. This was to be the first in a product line of grenade launchers from Milkor (Pty) Ltd.

Design

The Milkor Stopper is a riot gun used for riot control, designed to fire a 37/38mm or 40mm cartridge, which can be a 9mm Buckshot, Rubber ball buckshot, teargas canister, rubber shot cartridge or explosive. The weapon is simple to operate and all metal surfaces are treated with a coating for corrosion protection, plus long-life dry film lubrication. It fires one shot before reloading. It is a conventional single shot, break-open weapon (opening at the breech like an ordinary shotguns (not pump-action)) with a floating firing pin mechanism that ensures safety when accidentally dropped. As a security or assault weapon, it can be fired from the shoulder or like a pistol by hand. The components of the weapon are interchangeable (client dependent), providing a range of applications from Less Lethal 37/38mm to a 40mm Lethal weapon.
