The Cyelee CAT0-G brings the premium green emitter from the CAT G PRO into an accessible carry optic, combining extra brightness with twice the efficiency of Cyelee's red emitter. It is built from 7075-T6 aluminum with a large window, recessed buttons, and a top-loading battery tray found typically only in higher-priced optics.

The CAT0-G fits pistols with RMSc cuts, including 407K and 507K slides, and is suited to both carry and home defense use. Shake Awake technology activates the optic on any movement with no manual steps required. Sealed waterproof construction and a 50,000-hour battery life keep it ready in any conditions.

Why CAT0-G

Green Emitter in an Accessible Package
The CAT0-G brings the premium green emitter from the CAT G PRO into the CAT0 platform. Green sits at the peak of human visual sensitivity, making the dot faster to pick up across a wide range of lighting conditions. The green emitter also runs at twice the efficiency of a red emitter, supporting the optic's 50,000-hour battery rating.
Top-Loading Battery Without Removing the Optic
The CAT0-G uses a top-loading battery tray. Replace the CR1632 without removing the optic from your slide. Your zero stays intact across battery changes. This feature is uncommon at this price point and adds real value for daily carry users.
7075-T6 Construction with Recessed Buttons
Built from 7075-T6 aluminum with recessed side buttons that resist accidental activation during holster draws. The housing is sealed, waterproof, and built to a standard that competes above its price bracket.
Shake Awake: Always Ready
The CAT0-G activates on any movement with no manual button press required. It is live the moment you draw. Battery life is rated up to 50,000 hours on a single CR1632, making it a low-maintenance option for everyday carry.
IPX7 Waterproof
Electronics are sealed and rated to IPX7. Submersion-rated at 1 meter for up to 30 minutes. Built to perform in rain, humidity, and any field conditions without degradation.
Limited Lifetime WarrantyEvery CAT0-G is backed by Cyelee's Limited Lifetime Warranty, covering defects in materials and workmanship for the life of the optic.

CAT Family

The CAT family is built for compact and subcompact pistols on the RMSc/k footprint. Ultra-lightweight and low-profile, these optics are engineered for everyday carry and duty use. Shake Awake technology keeps the optic ready the moment you draw, while a crisp dot, wide window, and up to 50,000 hours of battery life mean it performs when it matters most.

Factory-Proven Reliability

Confidence is earned on the factory floor. Before any optic is approved, it undergoes a brutal testing protocol for shock, recoil, and environmental durability.
