Product Features
The GOWUTAR EP-20 combines a 3 MOA green dot with an enclosed emitter design, a fully multi-coated lens, and a durable 7075-T6 aluminum housing. Its 24.2 × 17.4 mm viewing window provides a practical sight picture for target shooting and range training, while 10 brightness settings help you match the reticle to changing light conditions.
With motion activation, a side-access CR2032 battery, and an ACRO footprint, this enclosed green dot sight brings everyday convenience to compatible pistol setups.
Enclosed Protection for Changing Conditions
An enclosed emitter design helps prevent water and debris from collecting on the emitter and interfering with the projected dot. The EP-20's fully enclosed optical system protects this critical area, making it easier to keep the aiming reference visible when conditions change.
With an IPX7 waterproof rating, the EP-20 adds reliable protection against water exposure—whether you're training in wet weather or caught in an unexpected downpour.
ACRO Footprint for Compatible Mounting Systems
The EP-20 uses the Aimpoint ACRO mounting standard. It requires a compatible ACRO-pattern interface or an appropriate adapter plate for your slide.
RMR & MOS Adapter Plates Included
Includes one RMR adapter plate and one MOS adapter plate. These plates provide mounting options for compatible RMR-cut slides and GLOCK MOS platforms, offering greater flexibility for compatible pistol setups.
7075-T6 Aluminum Built for Regular Use
The EP-20 features a 7075-T6 aircraft-grade aluminum housing with a hardcoat-anodized finish. Its 1500G shock-resistance rating supports the demands of repeated use on compatible firearm platforms.
At approximately 2.08 oz, the optic combines enclosed construction with a compact footprint for your pistol setup.
Motion Activation with Brightness Memory
Once powered on, the EP-20 automatically enters sleep mode after 240 seconds of inactivity to help conserve battery power. Movement wakes the green dot and restores the previously selected brightness level.
Manually switching the sight off also disables motion activation until you turn the sight on again.
A 3 MOA Green Dot for a Clear Aiming Reference
The EP-20’s 3 MOA green dot offers an easy-to-identify aiming point without covering a large portion of the target. It is a practical choice for shooters who prefer a green reticle for indoor practice and outdoor range sessions.
The 1× optical design and unlimited eye relief support flexible viewing, while the 24.2 × 17.4 mm fully multi-coated lens provides a clear view of your target.
10 Brightness Settings for Different Lighting Conditions
Adjust the green dot with the ▲ and ▼ buttons to suit your surroundings—from a well-lit outdoor range to a dimmer indoor setting.
3 night vision-compatible settings allow use with separate night vision equipment. The EP-20 itself does not provide night vision or illuminate the target.
Convenient Side-Access Battery Replacement
The EP-20 uses a CR2032 3V battery housed in a side-access compartment. Battery changes do not require removing the optic from its mount.
Battery life reaches up to 50,000 hours, depending on brightness and usage. Higher brightness settings consume more power.
