Reliable, modular, lightweight, piston-powered, the SKELI X11 CARBINE is everything you ever wanted in a next-generation modern sporting rifle. Developed from the ground up over a course of 5 years, the X11’s primary goal was to bring the greatest technological advancements in modern engineering. Crafted in the U.S.A, the SKELI X11 CARBINE presents many innovative features including advanced ergonomics, reliable piston operation, 3 position adjustable gas setting, and ambidextrous controls. Superior accuracy and extreme reliability were the core essential goals set forth in the development process of the SKELICO X11 weapons system, which in turn led to multiple Patents Pending. Weighing in at 6.8 lbs. unloaded, the SKELI X11 CARBINE is one of the lightest piston operated next-generation carbines in the world. The SKELI X11 CARBINE presents notable advantages over its competitors including a 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 SKELICO 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.
