It's the first on the market to feature a full metal receiver, CNC machined out of aluminum, done up in a very aggressive machined billet styling. This compact firecracker is a great main gun, or even a sidearm in close quarters situations, both indoor and outdoor. Internally the X9 features a reinforced gearbox with 9mm bearings for added performance. The trigger feels nice and snappy thanks to Classic Army's ECS MOSFET trigger system. Not only does the ECS system provide better trigger response, it also allows for programming of 3 to 5 round burst.
