The Cyelee CAT0 is a concealed carry red dot that delivers premium features at an accessible price point. It is built from 7075-T6 aluminum with a generously sized window, recessed buttons to prevent accidental activation, and a top-loading battery tray rarely found in optics at this price.

The CAT0 fits pistols with RMSc cuts, including 407K and 507K slides, and is purpose-built for defensive carry and home use. Shake Awake technology turns the optic on with any movement and requires no manual operation. Sealed waterproof construction and a 50,000-hour battery life ensure it is ready whenever it is needed.

Why CAT0

Top-Loading Battery Access
The CAT0 uses a top-loading battery tray, allowing battery replacement without removing the optic from your pistol. The CR1632 slides out from the top of the housing, keeping your zero intact across battery changes. This feature is rare at the CAT0's price point and adds meaningful convenience for daily carry users.
7075-T6 at an Accessible Price
Machined from 7075-T6 aluminum with recessed side buttons to prevent accidental activation during holster draws and re-holstering. The housing is sealed and waterproof, and the build quality matches what you'd expect from optics priced significantly higher.
Shake Awake: Always Ready
The CAT0 activates on any movement and requires no manual button press. It is live the moment you draw. Battery life is rated up to 50,000 hours from a single CR1632, making it a reliable option for everyday carry without frequent battery changes.
IPX7 Waterproof
The CAT0's electronics are sealed and waterproof to IPX7. Submersion-rated at 1 meter for up to 30 minutes. Rain, humidity, and harsh conditions are non-issues for the sealed construction.
10-Setting Illumination with NV Compatibility
Ten brightness levels give full control from bright daylight to two dedicated night-vision-compatible settings. The 3 MOA dot stays crisp and consistent at every level without washing out the sight picture.
Limited Lifetime Warranty Every CAT0 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.
