KWA RM4 A1 ERG 3.0

The KWA AEG3 RM4A1 Carbine is the first model in the new 3rd gen AEG family. This updated ERG model now shares the newest features of the recently introduced AEG 2.5 system, PLUS simulated recoil with KWAs patented Kinetic Feedback System. Highlighted by a Switch Life Extender to minimize the wear and tear on trigger contacts, the AEG 3 combines the ultimate AEG rifle with a more cost-effective training solution to provide players and professionals the best airsoft experience. Additional features include magazine cutoff compatibility combined with a quick-change spring for users to customize their KWA AEG rifle to their own specifications.

This updated ERG takes the professional airsoft training M4A1 model to a new level of performance with a one-piece full metal alloy upper receiver, a new rotary hop up and a PTS Enhanced Polymer Grip for added comfort. Rear-wired and Li-Po ready, the RM4A1 can still handle the extra power of LiPo batteries. The RM4A1 is also equipped with a reinforced metal gearbox utilizing KWA's unique 9mm ball bearing bushing combination and case hardened, upgraded precision metal gear sets. Heavy-duty springs and new high-torque motors are matched for optimum results. The KWA RM4A1 Carbine was engineered to outperform, offering ultra-high performance and training simulation straight out of the box.
