CAA Tactical M4S1 14.5" Sport Series AEG – Licensed and ergonomic M4 carbine from King Arms
Are you ready for an airsoft rifle that stands out from the crowd of traditional M4 models? The CAA Tactical M4S1 Sport Series is the result of a collaboration between King Arms (OEM) and the world-renowned firearms accessory manufacturer CAA. With its ergonomic design, unique M4S1 handguard, and sturdy metal gearbox, this rifle delivers a fantastic combination of precision and raw tactical functionality!
Workshop insight: What really sets this rifle apart is CAA’s well-thought-out ergonomic design. The distinctive M4S1 handguard provides an incredibly secure grip while featuring integrated Picatinny rails for additional accessories. The stock has a comfortable rubber buttpad, integrated QD sling mounts, and a smart built-in storage compartment for CR123A batteries (often used in tactical flashlights).This is a perfect and easy-to-handle rifle for both field and CQB games!
Durable nylon polymer and solid internals
The entire receiver, handguard, and stock are made from high-quality, fiber-reinforced nylon polymer. This provides an extremely robust and torsion-resistant construction that can withstand rough handling, while keeping the weight down to 2,900 grams for optimal mobility during long game days. Inside, you’ll find a rock-solid Version 2 metal gearbox with high-quality components, fully upgradeable with standard V2 parts in the future.
NOTE: To access the battery, simply tilt the handguard slightly out of the way. To remove the handguard completely, you must first unscrew the rail on the underside of the handguard!
The rifle comes with an authentic 140-round CAA Mid-Cap magazine.Since this is a mid-cap magazine, the BBs are fed continuously via an internal spring—meaning you don’t have to wind a wheel on the bottom, and you completely avoid the telltale rattling sound when running through the terrain.
