KJW Full Metal M4 CQB Gas Blowback Airsoft Rifle, Black

At 3500g, the KJW M4 has the heavy, full-metal feel of a real primary. It’s a solid, stable build with an adjustable stock that lets you shift the total length from 785mm to 865mm depending on your environment. This flexibility allows the airsoft rifle to transition easily between tight indoor spaces and open outdoor fields. It is a straightforward, professional-grade option for serious players.

Operating as a high-velocity GBB platform, this M4 stays consistently in the 450~480 FPS range for long-range engagements. It features a functional blowback system that adds significant recoil to every shot. The internal setup includes a 275mm inner barrel and a tool-adjustable hop-up, giving you the ability to fine-tune the rifle’s accuracy for long-range consistency. It is a capable primary for fields with higher FPS limits.

The muzzle is finished with 14mm CCW threading, supporting the direct mounting of tracers and suppressors. It ships with a 32-round magazine and utilizes a KJW-proprietary gas system specifically tuned for reliable cycling. The platform is optimized for use with Green Gas or propane, offering a durable, high-performance solution for players who need a gas blowback primary they can actually count on.
