Product Description


    Ultimate Reliability and Ease of Maintenance

    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.

    Ultimate Versatility

    This rifle was designed to be completely ambidextrous, and all the critical controls on it may be operated right- or left-handed. These include the 2-position safety, the magazine release, the bolt release and charging handle and the case-ejection selector, which determines whether spent brass is ejected to the right or left. 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 barrel is also easily replaceable in seconds, making is possible to use different lengths and calibers without any tools required. Lastly, the folding stock is adjustable for length of pull at the touch of a button, using a simple and rugged telescopic construction.

It also has Picatinny rails on both sides of and under the fore-end, which offer countless possibilities for easily adding lighting systems and other tactical devices.
