GOWUTAR GP-M 3 MOA MOS Direct-mount Red Dot Sight for Glock MOS Slides

Direct MOS Mount. Low Profile. 

The GOWUTAR GP-M is an open reflex sight designed for compatible GLOCK MOS pistols. Its direct-mount design eliminates the need for an additional adapter plate, keeping the optic close to the slide for a streamlined setup.

With a spacious viewing window, a crisp 3 MOA red dot, motion activation, and a side-loading battery compartment, the GP-M brings convenient operation and dependable construction to your everyday setup.

Direct Mount for Compatible GLOCK MOS Slides

The GP-M uses a dedicated MOS footprint for direct attachment to compatible slides. Its low-profile design supports co-witnessing with suitable iron sights; actual sight visibility depends on the pistol and iron-sight height.

Compatible models: GLOCK MOS Gen 3/4/5 configurations in the G17, G19, G20, G21, G22, G23, G34, G35, G40, G41, G45, and G47 model families.

Not compatible with: G43X MOS, G48 MOS, Gen 6 MOS, or standard non-MOS slides.

Check your exact pistol model, generation, and slide configuration before purchasing.

3 MOA Red Dot & Spacious Viewing Window

The 3 MOA red dot offers an easy-to-identify aiming reference while keeping the surrounding view open. A 25.2 × 17.2 mm fully multi-coated lens provides a generous viewing area within a compact housing.

With true 1× magnification and unlimited eye relief, the GP-M supports comfortable viewing with both eyes open. Adjust the brightness to keep the dot clearly visible without excessive glare.

10 Brightness Settings for Changing Light

Adjust the dot using the ▲ and ▼ buttons to match your surroundings. The GP-M offers eight daytime settings and two night-vision-compatible settings, allowing finer brightness control across different lighting conditions.

The two lowest settings are intended for use with compatible night vision devices. The GP-M does not provide night vision on its own.

Shake Awake with Brightness Memory

Once powered on, the GP-M automatically enters sleep mode after 240 seconds without movement. Movement wakes the red dot and restores the previous brightness setting.

This motion activation feature reduces unnecessary battery use between sessions. After turning the sight off manually, power it on again to reactivate motion sensing.

Side-Loading Battery, Keep Your Optic Mounted

The GP-M runs on a CR1632 3V battery. Its side-loading compartment lets you replace the battery while leaving the optic mounted, avoiding removal and reinstallation simply to access the battery.

Battery life reaches up to 40,000 hours, depending on brightness setting and usage conditions.

Durable 7075-T6 Aluminum Construction

Built from 7075-T6 aircraft-grade aluminum with a hardcoat anodized finish, the GP-M combines a compact form with durable construction. An IPX7 waterproof rating and 1500G shock resistance help it withstand moisture and recoil-related demands.
