KJW M4 Airsoft Gas Blowback Rifle w/ M-LOK Handguard, Two-Tone

The KJW M4 GBBR combines sharp two-tone aesthetics with tactical functionality. Its full-metal upper and lower receivers, metal outer barrel, and CNC-machined aluminum M-LOK handguard are balanced by an ergonomic, high-density polymer pistol grip and adjustable crane stock. At a nimble 3,500 grams, its overall length shifts quickly from 665mm to 745mm to master any battlefield environment.

Fueled by green gas or propane, the heavy-recoil mechanical bolt system mimics the operation of a real firearm in safe, semi-auto, and full-auto. This high-velocity platform clocks in at an impressive 450 to 480 FPS, using an integrated adjustable hop-up and a 275mm inner barrel to keep your shots laser-straight and consistent.

Out of the box, the package includes the rifle, a user manual, and one 32-round gas magazine. Please note that this platform utilizes a highly efficient, proprietary Tanio Koba-designed gas system, making it incompatible with standard Western Arms (WA)-spec internals or third-party M4 GBB magazines.

Equipped with a 14mm counter-clockwise (CCW) threaded muzzle for mock suppressors and tracer units, recommended performance upgrades include dropping in a precision, tight-bore inner barrel and a high-performance hop-up bucking to maximize shot consistency.

Note: Optic shown is NOT included.

This comes with a federally mandated blaze orange tip.
