Colt M4A1 Keymod 13"

The Colt M4A1 Keymod 13" is a full-length M4A1 with a long 13" KeyMod handguard that leaves room for a foregrip, light and laser without getting crowded. With an overall length of 790–880 mm depending on stock position, it is a versatile all-round rifle that works as well in woodland and on open sites as in more built-up scenarios.

The rifle is built in metal with a V2 gearbox and a 363 mm inner barrel, and the battery is stored in the adjustable crane stock. It is a classic, well-proven M4 layout where you can adjust the length of pull to your own shoulder and kit, and where spare parts are available everywhere.

M4A1 with long KeyMod handguard

The long rail and the proven M4 layout make the rifle easy to customise and maintain.

• 13" KeyMod handguard: KeyMod lets you mount rail sections exactly where you need them, so the handguard stays slim and easy to grip – unlike a RIS handguard with rails all the way round.
• Metal receivers: Upper and lower receiver are metal, giving a stiff, tight fit without the wobble often found on cheaper polymer models.
• V2 gearbox and long motor: The M4 standard means gears, piston, spring and motor can be upgraded with common aftermarket parts.
• Crane stock with battery space: The adjustable stock holds a nunchuck battery, so the battery sits protected and the handguard stays free for accessories. The connector is mini Tamiya.
• 350-round hi-cap magazine: The magazine gives many shots per refill, and the M4 platform takes standard AEG magazines if you want to switch to mid-cap or real-cap.

Maintenance and safety
Always remove the battery after use and for storage, and charge LiPo batteries under supervision in a LiPo safety bag. Clean the barrel with a cleaning rod and a dry cloth when accuracy drops, and only use silicone-free oil on the external metal parts. Store the rifle locked away and out of reach of children, transport it in a closed bag, and always wear approved eye protection on site. Check the rules on buying and owning airsoft replicas in your country.
