The factory-installed ROMEO-X COMPACT optic sits incredibly low to the slide so you can enjoy co-witness with the included standard height iron sights, giving you a consistent, familiar sight picture. This is a complete slide assembly, including all internal slide parts, and front and rear XRAY3 Day/Night sights. Barrels and recoil spring assemblies are sold separately.
