The Beretta ARX 100 is the end result of years of design, development, and engineering work by Beretta to produce the world's best third generation battle rifle.
The Beretta ARX 100 was designed to have the highest level of reliability. Making use of a constant contact short stroke piston ensures that the ARX 100 will feed and fire any 5.56 ammunition in the toughest environments. The receiver of the ARX 100 is made from space age polymer that requires no lubrication for operation making maintenance and operability the same in any environment. To allow the ARX 100 to be maintained by soldiers in the field with as much ease as possible the ARX 100 uses no pins or locking mechanisms, take down of the ARX 100 is completely tool free
The Beretta ARX 100 is designed to allow complete ambidextrous operation. Every single critical component can be configured to operate for either right or left handed shooters. These critical components include the safety selector, magazine release, bolt release, charging handle, and case-ejection selector. The case-ejection selector controls whether or not the spent brass is ejected from the right or left. The included flip-up front and rear sights that are standard on the ARX 100 offer an easily adjusted diopter system that can be ranged from 100 to 800 yards. The barrel on the ARX 100 is a quick change barrel that can be removed in seconds, allowing you to use different length and caliber barrels with no special tools. The folding stock is also adjustable for length of pull and is of a telescopic design.
