WAIT, MY LENS IS TILTED
Cuinfi® 1x24 features an open emitter design with the emitter located behind and below the reflective glass window lens. Light from the emitter is reflected from this specially coated lens in a carefully controlled manner thanks to the lensesshape and curve. The positioning of the ens is very deliberate, so there is nothing wrong with a "tilted"lens. The optical design demands the lens be positoned in this way.


INSERTING & CHANGING THE BATTERY
Cuinfi® 1x24 uses a CR1632V battery which is included in the box, but not pre-inserted into the optic.
1. Insert the CR1632 battery from underneath, with the[+]side facing the down and the [-]side facing up.
2. Automatic variant: Confirm that the optic has powered up by observing
the 2 MOA red dot.
Manual variant: Confirm that the optic powers on by pressing the brightness UP “▲” button.

POWER & BRIGHTNESS
Cuinfi® 1x24: Manual
On/Off
• Press the brightness UP “▲” button to power on.
• Hold the brightness DOWN “▼” button for 3 seconds to manually power off.
• When the sight is powered back on it will automatically return to the previous brightness level.


BRIGHTNESS
• Cuinfi® 1x24 is equipped with 10 brightness settings.
• Use the brightness UP “▲” and brightness DOWN "▼" buttons to adjust brightness level.
• When using low brightness settings, ensure sufficient reticle contrast against the target.
• Medium brightness settings are ideal for indoor shooting ranges and home defense situations.
• The highest two brightness settings are daylight bright and should only be used in very bright conditions. Using these settings in darker conditions will cause unwanted glare and reticle bloom.
SHAKE 'N WAKE
• After approximately four minutes without sensing movement, Cuinfi® 1x24 will shut off illumination to save battery life. While "asleep" the battery willdraw no power. As soon as movement resumes, the optic will immediately "wake" and resume its previous brightness level.
• Cuinfi® 1x24 does not incorporate a timed fully-shutdown feature that requires the user to press a button to wake.
• Shake’N Wake is seamless and intended to be unobtrusive to the user. It is not a mode that can be activated and deactivated, it is hard wired into the function of the optic.
MOUNTING
BEFORE INSTALLATION, CONFIRM THE FIREARM IS UNLOADED.
• Cuinfi® 1x24 is compatible with the industry standard RMR footprint. Some handguns use interchange-able plates to configure the mounting area.
• With the battery instaled
Place the mounting in the mounting, making sure the location is appropriate.

Follow the slide manufacturer's torque recommendations. If none are specified, a safe bet is to use blue thread-ocker on the screw threads and torque to no more than 15 inch-pounds.
MULTI - RETICLE
The multi-reticle variant provides 3 reticle options, including a 2 MOA center dot.
At 50 yards, a 2MOA dot is 1'', or 2 MOA is 2'' at 100 yards.
When changing between reticle options, your subtensions will not change. This allows for reliability and versatility across firearm platforms.

RETICLE ADJUSTMENTS
Cuinfi® 1x24 features a 2 moa dot + 48 moa circle MOA red dot reticle. One Minute of Angle is equivalent to approximately 1” at 100 yards,or. 75” at 75 yards. 50” at 50 yards, etc.

MAINTENANCE
Before cleaning your optic lens make sure to blow away any dust or grit on the lens to prevent the lens from being scratched while cleaning. Always use a soft cloth when cleaning your lens.
PARALLAX
Cuinfi® 1x24 is designed to be parallax free at 33 yards. At distances closer than 33 yards, parallax erroris very minimal and will not lead to appreciable point of impact shift. At distances past 100 yards, some parallax will be observed. When using your sight at close range, keep in mind that the entire window is available for aiming. If you can perceive the reticle anywhere in the window, you can use it as a point of aim. For shooting past 100 yards, keeping the reticle more centered in the window will result in more consistent hits on target.
CUINFI 50,000 ROUND GUARANTEE
If your optic fails prior to firing off 50,000 live fire rounds, we will repair or replace it for free. Nope, we’re not tracking shot data. We’ll go by the warrior honor code and your best estimation on whether or not the optic failed prior to using it for at least 50,000 rounds.

Powered by a CR1632 Battery Red Dot, the Phantom 1x24 offers an impressive 4,000+ hours of constant-on use and up to 50,000 hours of real-world battery life—eliminating frequent battery replacements. The manual variant features Shake N Wake Red Dot motion-sensing technology: after 4 minutes of inactivity, the sight shuts off illumination to conserve power, and instantly “wakes” when movement is detected, resuming the previous brightness level seamlessly.
Equipped with a Red Multi-Reticle design, this sight provides three reticle options: a precise 2MOA dot, a 48MOA circle, and a combined dot+circle configuration. At 100 yards, the 2MOA dot covers just 2 inches, ensuring long-range accuracy, while the 48MOA circle aids in fast target acquisition at close distances. With 10 brightness settings (8 daylight + 2 night vision-compatible), the reticle adapts to any lighting condition—from dim indoor ranges to bright outdoor environments.
Featuring a 1 Click=1MOA adjustment system, the Phantom 1x24 allows for precise windage and elevation tweaks with a total adjustment range of ≥90 MOA. The sight is parallax-free at 33 yards, with minimal parallax error at distances under 33 yards and consistent performance up to 100 yards. Its Fully Multi-Coated lens enhances light transmission, delivering clear, bright imagery while reducing glare and reflections.
Built to withstand harsh conditions, the Phantom 1x24 boasts IPX7 Waterproof Red Dot rating (protected against submersion in 1m of water for 30 minutes) and 1500G Shockproof Red Dot durability—resisting recoil from even high-powered pistols. Backed by the 50000 Round Guarantee Red Dot, Cuinfi offers free repair or replacement if the optic fails before 50,000 live rounds, trusting in the shooter’s honor for verification.
Weighing just 60g, the Phantom 1x24 is one of the lightest red dot sights in its class, ensuring it won’t weigh down your pistol slide. Its compact dimensions (1.77”×1.22”×1.42”) make it ideal for EDC, fitting seamlessly on slimline pistols without compromising handling.
Crafted from 6061 Aluminum Red Dot alloy with a hardcoat anodized finish, the sight offers exceptional corrosion resistance and structural integrity. The open emitter design places the emitter behind and below the reflective glass lens—an intentional optical design that creates a “tilted” lens appearance (completely normal, as it optimizes light reflection for a crisp reticle).
Intuitive brightness buttons (“▲” for power-on/brightness up, “▼” for brightness down/3-second hold to power off) ensure quick adjustments in the field. The sight retains the previous brightness level when powered back on, eliminating the need to readjust settings mid-use. It’s compatible with the industry-standard RMR Footprint Red Dot, fitting most modern pistols with interchangeable mounting plates.
The Phantom 1x24’s ultra-compact size and lightweight design make it perfect for EDC pistols. Its fast-acquisition reticle and Shake N Wake technology ensure readiness at a moment’s notice, whether for self-defense or casual shooting trips.
Engineered for high-stress situations, the sight’s rugged build, waterproof rating, and precise reticle make it a reliable tool for law enforcement officers. The 2MOA dot enables accurate shots at varying distances, while the open emitter design resists debris buildup in tactical environments.
Medium brightness settings are ideal for indoor ranges and home defense, providing clear reticle contrast without glare. The multi-reticle system adapts to close-quarters scenarios (48MOA circle) and longer-range practice (2MOA dot), making it a versatile choice for recreational and defensive shooting.
The “tilted” lens is a deliberate part of the open emitter design. The emitter is positioned behind and below the reflective glass, and the lens’s curve and angle are optimized to reflect light precisely—this is not a defect, but a key feature of the optic’s performance.
The sight uses a CR1632 Battery Red Dot (included in the box, not pre-inserted). Insert the battery from underneath with the [+] side facing down and [-] side up. For the automatic variant, confirm power by checking the 2MOA red dot; for the manual variant, press the “▲” button to power on.
No—Shake N Wake Red Dot is hardwired into the optic’s function for seamless battery conservation. It shuts off after 4 minutes of inactivity (drawing no power) and wakes instantly with movement, requiring no manual activation.
