The world's first production green gas-powered, open bolt M249 airsoft machine gun. Lightweight aluminium construction with steel-reinforced critical components keeps weight to just 4kg, reducing shooter fatigue during extended skirmishes. Separate gas reservoir and BB magazine system—gas stored in M4/AR-15 style tank, BBs in lightweight polymer magazines inserted into the feed tray—delivers realistic operation without the bulk of traditional designs. Shoots consistently and accurately out of the box, handling heavier 0.3g BBs with ease. Genuine field-stripping and takedown mirrors real steel M249 operation, ideal for those learning actual LMG mechanics. Correct markings throughout, adjustable hop-up, and satisfying gas blowback recoil replace the motor whine of AEG alternatives. Vibrating ammo belt (sold separately) adds immersive realism. Dry-fire capable. Includes 100-round magazine and M4/AR-15 style gas reservoir. Full auto, CCW barrel thread.
