AREX Delta X OR 9MM | Optic Ready 4″ | 815537023954

The AREX Delta X OR is an optic-ready, striker-fired 9mm handgun featuring a 4" barrel and a modular frame that accepts interchangeable backstraps. The slide has a black nitride finish and the pistol ships with an optics plate kit for electronic red-dot sights. This design preserves a removable front frame insert that contains the serialized fire control mechanism while allowing other frame components to be customized.

For pairing under $1,000, a compact red-dot such as the Vortex Venom is suitable for the Delta X OR’s optics cut and footprint. Typical uses include everyday carry where legal and range/competition practice.
