X11 Features

Additive Technology

The X11 is the first production firearm to use additive manufacturing to allow customization.

Fully Ambidextrous

All controls are fully ambidextrous, with the option of left or right hand ejection making the X11 the most advanced carbine platform on the market.


60 second quick change barrel system allows the operator to change calibers and barrel configurations. Takes AR-15 magazines and FCG's.



Reliable, modular, lightweight, piston-powered.. the X11 is everything you ever wanted in a next-generation modern sporting rifle. Developed from the ground up over nearly a decade, the X11’s primary goal was to bring the greatest technological advancements in modern engineering. Crafted in the U.S.A, the X11 presents many innovative features including advanced ergonomics, reliable piston operation, 2 position adjustable gas setting optimized for suppressor use, and ambidextrous controls. Superior accuracy and extreme reliability were the core essential goals set forth in the development process of the X11 weapons system, which in turn led to multiple Patents Pending.

Weighing in at 6.4 lbs. unloaded, the X11 is one of the lightest piston operated next-generation carbines in the world. The X11 presents notable advantages over its competitors including, 60 second free floating quick-change barrel system for various calibers and configurations, trouble free maintenance, and an array of modular and ambidextrous features. The quick-change barrel system maintains its zero after repeated removal of different barrel configurations and calibers and is capable of both right and left hand ejection by simply changing out the bolt. The new patented gas adjustable floating piston system is integrated independently from the barrel structure, making caliber conversions lighter for carry on personnel, and lowering the overall costs of ownership. To further the X11’s modular features, it utilizes AR-15 drop in fire control groups. Caliber changes can be conducted by the operator in under 60 seconds. Manufactured 100% in the U.S.A. using U.S.A. materials and resources.
