The Beretta ARX100 Semi-Auto tactical rifle features a constant contact/short-stroke gas piston system that makes it feed and fire under the most unforgiving conditions. 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. The Beretta ARX100 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, magazine release, bolt stop, charging handle, and the case-ejection selector, which determines whether spent brass is ejected to the right or left.  The Beretta ARX100 Semi-Auto rifle is equipped with Fold-up iron sights, a 30 round magazine, and matte black finish. This rifle is one of the lightest piston driven 5.56 rifles out there.
