Launcher
M32A1-LW
The Ultimate Force Multiplier
Overview
The M32A1-LW Multiple Grenade Launcher represents the next evolution of Milkor's combat-proven 40 mm platform, combining reduced weight, modern ergonomics, and expanded capability in a six-shot, shoulder-fired system. Tested and qualified in accordance with U.S. Department of Defense and NATO STANAG standards, the M32 family is fielded by the U.S. military and allied forces worldwide.
Chambered for all standard NATO 40×46 mm low-velocity, lethal, and less-lethal ammunition, the M32A1-LW is also qualified to fire 40×51 mm medium-velocity munitions, extending effective engagement distances to 800 meters. Milkor's proprietary progressive rifling enhances projectile performance while preserving compatibility across the full spectrum of NATO ammunition.
The lightweight configuration incorporates a modern M-LOK handguard, an optimized medium-velocity cylinder, and an Aimpoint Acro-compatible sighting system, reducing system weight without compromising durability or firepower. M-LOK attachment points support mission-essential accessories such as lights, lasers, and vertical grips, while compatibility with mil-spec AR-pattern stocks allows operators to tailor the weapon to individual preferences.
Designed within the ergonomic requirements of TOP 3-2-504, the M32A1-LW enables operators to configure each cylinder with a mission-specific mix of lethal and less-lethal rounds. Capable of delivering all six grenades in less than three seconds, the launcher can saturate an area approximately 20 × 60 meters before reloading.
The M32A1-LW delivers pinpoint accuracy to 125 meters with low-velocity ammunition and 250 meters with medium-velocity ammunition, with maximum effective ranges of 400 meters and 800 meters respectively, providing unmatched flexibility across military, law enforcement, and security operations.
