Product Summary

The ARX100 was engineered with one purpose in mind: to be today’s best tactical semi-auto rifle. It takes the concept of a modular rifle to futuristic levels, while maintaining an absolutely simple operation that make it ultra-reliable. The ARX100 features a constant contact/short-stroke gas piston system that makes it feed and fire under the most unforgiving conditions. The lightweight technopolymer receiver allows for reliable operation with virtually no lubricants. To make maintenance easy and trouble-free, this rifle has no pins and can be completely disassembled in a matter of seconds with no tools at all. All of the critical controls on the ARX100 are completely ambidextrous. Case ejection can be switched from right to left with the simple push of a button. In addition, the cold hammer-forged barrel can be removed and replaced with various lengths and calibers in a matter of seconds. The flip-up backup sights that come standard on the ARX100 are also versatile, offering an easily-adjustable diopter system ranged from 100 to 800 yards. The folding stock is adjustable for length-of-pull at the touch of a button, using a simple and rugged telescopic construction. This rifle’s stock, metal, and bore are all in excellent condition.
