Cyelee CAT-PRO Open Reflex Sight – 3 MOA Red Dot, RMSc Footprint with Motion Deactivated Standby

The Cyelee CAT G-PRO Open Reflex Sight combines a compact RMSc footprint with a clear 3 MOA red aiming point. Its low-profile format supports compatible optics-ready platforms where space and sight visibility matter. The red reticle provides a defined reference point without filling the viewing window, helping the user maintain awareness around the intended point of aim.

Motion Responsive Illumination

Motion Deactivated Standby reduces unnecessary battery use while the sight remains still. Movement restores illumination, eliminating the need to manually reactivate the dot during normal handling. The optic offers 10 adjustable illumination settings, including 8 daytime levels and 2 night vision settings, so brightness can be matched to different lighting environments and viewing equipment.

RMSc Footprint and Side Battery Access

The CAT G-PRO uses the RMSc, 407k, and 507k footprint pattern for installation on compatible slides, mounts, or adapter plates. A side-loading CR1632 battery compartment allows battery replacement without removing the optic from its installed position. This helps preserve the mounting setup during routine battery maintenance.

Clear Open Reflex Viewing

The open reflex design uses a 21 x 16.5 mm viewing window and 1x magnification. Parallax-free viewing and unlimited eye relief support flexible eye placement behind the optic. An IPX7 waterproof rating adds protection against wet conditions, while the compact profile keeps the sight suitable for equipment where mounting space is limited.
