Product Info for Cyelee Optics CAT SRS6 PRO 1x21x16.5mm Reflex Red Dot Sight

CAT SRS6 PRO: Small Size. Full Power.image

The Cyelee CAT SRS6 PRO is a micro red dot built for subcompact pistols. It is tough, clear, and fast to use.

It features the STIG-RS (Astigmatism Relief System) reticle, made specifically for users with astigmatism. Feedback is clear: many see the benefits of using Cyelee STIG-RS LED emitters. Additionally, its larger 6MOA circle allows for lower brightness settings without harming reticle acquisition time.

Made for daily carry and duty use, the CAT SRS6 PRO fits slides and plates using the Shield RMSc or 407k/507k footprint, ensuring easy setup with many popular pistols.

It also has Motion Deactivated Standby; it sleeps after four minutes of no motion and wakes instantly when moved. With a waterproof housing, sealed electronics, and a Super LED for up to 50,000 hours of power, this optic delivers simple, trustworthy performance.
