Beretta made waves on the very first day of the 142nd NRA Annual Meetings & Exhibits with the unveiling of its new ARX100 Multi-Caliber. The rifle is equipped with a cold hammer forged barrel that can be removed and replaced with various lengths and calibers in a matter of seconds—the first two configurations available will be 5.56 and .300 AAC Blackout.

The gun sports a constant contact piston system, allowing it to easily feed and fire, even under the most unforgiving conditions. Its lightweight, technopolymer receiver allows for reliable operation, with little lubricant.

Better yet, the ARX100 is completely ambidextrous. All of the firearm's critical controls can be adapted to suit a left-handed shooter—and a selector near the rear of the gun allows the user to switch between left or right spent casing ejection configurations.

Technical Specifications:

Model: ARX100
Action: Semi-Auto
Caliber: 5.56x45
Capacity: 30 Rounds
