Milkor MGL

Operating mechanism The MGL is a low-velocity, shoulder-fired 40 mm grenade launcher with a six-round spring-driven revolver-style magazine capable of accepting most 40×46mm grenades. The spring-driven cylinder rotates automatically while firing, but it must be wound back up after every reloading. Features The MGL grenade launcher consists of a lightweight, progressively rifled steel barrel, sight assembly, frame with firing mechanism, spring-actuated revolving cylinder magazine, and a folding stock. The weapon has a fire selector safety switch just above the rear pistol grip which can be operated from either side. The launcher cannot be accidentally discharged if dropped. The launcher is loaded by releasing the cylinder axis pin and swinging the steel frame away from the cylinder. The rear of the cylinder (including the pistol grip) is unlatched and pivoted counter-clockwise to expose the chambers during reloading. By inserting the fingers into the empty chambers and rotating the aluminium cylinder it is then wound against its driving spring. The grenades are then inserted into the chambers, one-by-one (because the cylinder cannot be removed), the frame closed, and the axis pin re-engaged to lock. When the trigger is pressed a double-action takes place and the firing pin is cocked and released to fire the grenade. Gas pressure on a piston unlocks the cylinder and allows the spring to rotate it until the next chamber is aligned with the firing pin, whereupon the next round can be fired. If a misfire occurs the trigger can be pulled repeatedly. Sights The Y2, amongst other models, is equipped with the Armson Occluded Eye Gunsight (OEG), a collimator sight which provides a single aiming post. The shooter aims with both eyes open and the post is superimposed onto the target, both being in focus. The OEG on the Y2 is designed as an aid to range estimation, the post being equal to the height of a man at . It is also fitted with tritium illumination for low light operation which has a life of at least ten years. The range quadrant is graduated in increments. Accessories Each MGL is supplied with a sling, cleaning kit, and user's manual. ==Variants==

Several upgrades were made to the original design in the last decade. After over 12 years of production, and more than a decade of user feedback from different countries around the world, it became evident that a redesign of some component groups would make the weapon even more user-friendly and reliable while also simplifying maintenance. This development, known as the MGL Mk-1 was introduced to the market in 1996. All weapons previously supplied can be upgraded to the Mk 1 configuration. Parts, such as the steel barrel, are interchangeable with a minimum of workshop modifications involving a few special tools and cutting dies. Two "product improved" variants were introduced in 2004. The first is the Mk 1S, which replaces the aluminum frame of the Mk 1 with a stronger stainless steel body, a conventional trigger unit, and Picatinny rail support at the top, sides and bottom of the forend. The second variant is the Mk 1L, with the same features as the Mk 1S, but with a long cylinder to fit special-purpose grenades such as tear gas canisters and less-lethal impact rounds that are too long to fit in the other models' shorter cylinder. The Mk 1L also features a sliding buttstock. In 2006, the Milkor 37/38mm Multiple Anti-Riot (MAR) replaced the 40mm less-lethal Yima. The MAR is largely identical to other MGL models, but is adapted to fire standard 37/38mm less-lethal riot control rounds available today. Rounds can be fired in rapid succession of six rounds in less than 3 seconds (operator dependent) and has a standard six-shot area coverage of at least . Milkor USA Milkor USA, Inc. is an American company that produces copies of the Milkor MGL. Milkor (Pty) Ltd has no affiliation or working relationship with Milkor USA. In 2014, Milkor USA dropped the MGL-105 and MGL-140, and introduced a shorter-barreled variant, the M32A1. Despite the shorter barrel ( instead of ), it weighs the same as the M32, because its receiver, stock and other parts of the weapon were strengthened, in anticipation of higher pressure medium velocity rounds sought by United States Special Operations Command. The M32A1 has been adopted by the U.S. Marine Corps as the M32A1 Multi-shot Grenade Launcher, and by USSOCOM as the Mk 14 Mod 0. ==Users==
