This listing is the ROMEO-RS Compact Rose, 3 MOA red, black housing with Rose Gold chassis, SOR02138 only.

Reinforced Steel, Rose Gold Chassis

ROMEO-RS means Reinforced Steel. A skeletonized steel chassis is molded into a high-strength polymer housing. On Compact Rose, SIG specifies a custom Rose Gold PVD steel chassis and a matching Rose Gold reticle control button. Spec-table color is Black / Rose Gold. Threaded metal inserts take the mounting torque and the side-load battery tray; more metal inserts back the windage and elevation mechanisms. Steel recoil pins add lock-up so the optic does not walk laterally in the cut.
