    KWA VM4A1 Variable FPS Airsoft Rifle

    KWA has reengineered their gearbox with new improvements that leave other AEGs in the dust. KWA's new Variable Performance System allows this AEG to have it's spring changed as well as FPS fine-tuned all without having to remove the gearbox from the rifle. In addition to that, KWA has also added a Switch Life Extender to prevent damage to the trigger contacts when using high voltage LiPO batteries. The old motors were swapped out with new and improved High Torque motors  to allow a wide array of AEG springs to be used for many different FPS ranges. Upgraded high-speed gear sets allow this AEG to reach 18+ BBs per second when firing using a LIPO battery. KWA removed their two-piece hop up system and replaced it with an easier to use Rotary style hop up. The one-piece upper receiver is rock solid and does away with the two-piece style flaws. KWA also included a magazine cut off system along with their 30/120 BB capacity adjustable mid-cap magazines.
