Used Kwa Full-Metal Vm/M Carbine Electric Airsoft Rifle

The KWA VM4A1 2.5 Full Metal Airsoft AEG Carbine is a battle-tested upgrade for serious Milsim and field players seeking unmatched reliability and customization. This pre-owned rifle has been rigorously inspected and tested to ensure peak performance, ready for intense skirmishes or recreational airsoft engagements. Engineered with KWA’s innovative Variable Performance System (VPS), users can fine-tune the velocity between 360-380 FPS using the included adjustment tool—ideal for adapting to different game rules or play styles.

Constructed with a robust full-metal one-piece upper receiver and reinforced metal gearbox, this carbine combines durability with precision handling. The upgraded V2.5 gearbox houses a high-torque motor and hardened metal gears, delivering consistent firepower even under prolonged use. To extend its longevity, the integrated switch life extender minimizes contact wear, reducing downtime between matches.

For tactical versatility, the VM4A1 features a rotary hop-up system for accurate mid-range shots and a magazine cutoff that halts fire when switching from full-auto to semi-auto modes—a must-have for scenario-based gameplay. The PTS Enhanced Polymer Grip ensures a secure, ergonomic hold during extended sessions, while its Li-Po battery compatibility (7.4v recommended) offers rapid trigger response and sustained power output.

Designed for real-world readiness, this rifle supports both 30-round and 120-round KWA M4/M16 magazines, providing flexibility for different mission demands. The threaded barrel (14mm negative) allows easy attachment of aftermarket accessories like flash hiders or compensators, while the included Bushnell sight protector safeguards optics during transport.

Supplied with everything needed to start playing—two magazines (one high-capacity), a manual, FPS tool, and an OD Green carrying case—the VM4A1 2.5 strikes a balance between performance and practicality. Whether dominating field ops or building a competitive Milsim setup, this carbine’s rugged build and adjustable features make it a standout choice among pre-owned airsoft rifles.

Perfect for experienced players or newcomers aiming to step up their gear game, this rifle blends classic M4A1 design with modern upgrades like rear-wired internals and reinforced components. Its smooth operation and ability to handle high-performance batteries ensure it stays ahead in fast-paced airsoft battles—without compromising on dependability or comfort.
