This listing is for the complete OEM factory slide assembly with 4” threaded barrel for the Ruger RXM. Finished in durable Black FNC Nitride, the assembly features a factory optics‑ready cut for miniature red dot sights and comes with factory‑installed sights: a tritium front sight for low‑light visibility and a factory steel rear sight (non‑adjustable) at co‑witness height. The integrated 4” threaded barrel makes this the factory configuration for applications requiring muzzle accessories or suppressor readiness.

Engineered to Ruger OEM specifications for correct fit and function, this complete slide assembly with threaded barrel is ideal for replacement, restoration, or building a factory‑spec threaded‑barrel RXM.
