The ARX100 is a semi-automatic civilian version of the Beretta ARX160 military rifle.  The ARX100 is almost identical to the ARX160, except that it does not have the full-auto capability.  It became available in the U.S. market in late 2014.

The ARX was developed for the Italian military in the early 2000s and first issued in 2008.  It has seen combat service in Afghanistan with the Italian armed forces.  It is also used by the armies of Albania, Bahrain, and Turkmenistan and by special forces and police forces in Kazakhstan, Mexico, Pakistan, and United States.

The ARX is perhaps the most ambidextrous rifle in production.  It has safeties, bolt releases, and magazine releases on both the right and left sides but what really sets it apart is the ability to have charging levers or ejection out either the left or right sides.  This can also, all be done without tools.

The ARX uses a short stroke piston, instead of gas impingement (like the M16).  This enables the rifle to run very clean and the rifle is in fact designed to run without lubrication.  The barrel and bolt are also interchangeable, again without tools.  This enables the gun to use both 16 and 11 barrels in 5.56x45 NATO and 7.62x39mm (potentially 6.8 SPC and .300 AAC Blackout).  

The ARX has a full length picitanny rail on the top, 4” sections on each side, and a 1.5” section on the bottom.  These allow a wide variety of optics and accessories to be fitted.  There is also a special length of rail enabling the attachment of a Beretta 40mm grenade launcher. It also, has a 4 position stock that folds to the right and allows the gun to still be fired when folded.
