The Knight's Armament Stoner 99 is the lightest weight machine gun in its class. Designed to be maneuverable in tight spaces yet effective at long ranges, the Stoner 99 LMG is a revolutionary innovation for machine guns. The airsoft version is fully licensed by Knight's Armament Company and made by Classic Army. Externally, this airsoft gun replicates all features found on its real-steel counterpart and is constructed out of CNC-machined aluminum. The upper receiver is railed for red-dot or magnified optics and the heatshield/handguard also integrates 20mm RIS rails for bipods, foregrips, PEQ/lasers, and more. The pistol grip is a standard M4/AR-15 style and can be replaced with other aftermarket pistol grips. The electric auto-winding box magazine replicates the Stoner 99's with the exact dimensions and features the iconic nylon cover. Internal features include a newly designed metal 8mm gearbox, high-torque motor, 18:1 steel gears, quick-change spring guide, lightweight nylon piston with aluminum piston head, and an adjustable dial hop-up. If you need a dependable airsoft support weapon, the Knight's Armament Stoner LMG tops the list.
