The acronym “RDO” indicates that this variant is ready for mounting red dot optics. Adapter plates are included for mounting point sights with Docter, Trijicon and C-More footprints on the metal slide of the APX.

Like the original, this gas-operted airsoft pistol produces a convincing recoil. The low barrel axis ensures better control and accuracy in rapid firing. Pronounced serrations on the heavy metal slide allow it to be grasped almost anywhere. The polymer frame has a non-slip finish and a Picatinny rail on the dust cover for optional accessories.

The front sight is adjustable in windage for optimal results even with iron sights, and the Shoot-Up can also be adjusted. The Beretta APX RDO has a reversible magazine release, allowing it to be used by left-handers. A trigger safety prevents accidental firing.
