Built from durable, lightweight nylon fiber reinforced polymer, this rifle can take the punishment of hard game play and keep on shooting. The gearbox is the ARES version 2 gearbox, made from durable cast zinc alloy with a quick-change spring system for easy adjustment of FPS for wherever you play.

The gearbox also features the gambit of industry standards such as metal gears and high strength polymer piston parts for maximum rate of fire. The textured grip houses a high-torque motor that pulls nearly any spring you may use with the quick-change system.
