Overview
The ROMEO4XT-PRO is a compact rifle red dot that packs a lot of features into a small, lightweight package. The 4XT offers 50,000 hours of battery life from a standard AAA battery, several flip cover options, a killflash, and four swappable reticles. The included mount comes in at absolute height, but the included spacer can be installed to bring the optic up to a lower 1/3rd co-witness.
