Beretta Rx4 Storm

The Beretta Rx4 Storm is a semi-automatic rifle chambered in .223 Remington / 5.56x45mm NATO, introduced in 2005 as part of Beretta's Storm weapon family. It uses a short-stroke gas piston system for reliable operation and reduced fouling compared to direct impingement designs. The Rx4 features a polymer frame with a unique overmolded rubber surface for a secure grip, a side-folding stock, and a Picatinny rail system. It is offered with 5, 10, and 20-round magazines. The Rx4 Storm was designed for law enforcement, military, and civilian sporting use.
