KWA LM4 PTR and LM4D Green Gas Magazine, 40 Rounds

This upgraded version is 25% lighter than previous generations to reduce your field loadout while maintaining structural strength. The rugged, precisely machined metal alloy housing fits standard magwells perfectly and drops free for fast reloads. It holds 40 rounds and includes a built-in dry-fire switch for realistic weapon training and reload drills without feeding BBs.

The internal green gas reservoir uses premium rubber seals to maximize gas efficiency. Built for demanding training cycles, all internal valves, seals, and impact buttons are modular and easy to replace with factory components. To preserve peak consistency, users should routinely inspect the gas release valves and integrated feed lips for debris. Maintaining an airtight seal against the bolt carrier group is as simple as applying a few drops of medium-viscosity silicone oil to the top main seal and intake valve. For a max-capacity charge free of air pockets, always hold the green gas canister vertically and fill the magazine upside down for 3 to 5 seconds.

Features:

• Intact, crack-resistant high-strength feeding lips
• O-ring sealed premium gas intake fill valve
• Smooth, non-binding mechanical gas release button
• Lubricated main rubber seal for optimal bolt carrier group compression
