Product Features

Three Reticle Options. Multiple Platforms. One Versatile Optic.

The GOWUTAR A20C features three selectable red reticles—a precise 2 MOA dot, a fast 38 MOA circle, and a combined circle-dot. Its standard RMR footprint and included low-profile Picatinny mount expand compatibility across suitable pistols, rifles, and shotguns. A rugged 7075 aluminum housing, Shake Awake technology, and IPX8 waterproof protection keep it ready for demanding shooting applications.

1. Three Selectable Red Reticles
Choose between a precise 2 MOA dot, a fast-acquisition 38 MOA circle, or a combined circle-dot reticle. Hold the ▲ button for three seconds to cycle between the three reticle options for different distances, target sizes, and shooting styles.

2. RMR Footprint with Picatinny Mount
Install the A20C on a compatible RMR-cut pistol slide or RMR adapter plate. The included low-profile Picatinny mount also allows the optic to be configured for compatible rifles, shotguns, and Picatinny or Weaver-style rail platforms.

3. Shake Awake with Up to 40,000 Hours of Runtime
After approximately 240 seconds without movement, the reticle automatically turns off to conserve battery power. Movement instantly reactivates the optic at the previous brightness setting. Battery life ranges from approximately 160 to 40,000 hours depending on brightness and use.

4. Rugged 7075 Aluminum Construction
The A20C is constructed from 7075 aircraft-grade aluminum and rated for IPX8 waterproof protection and 1800G shock resistance. Its durable housing is engineered to withstand recoil, impact, rain, and demanding outdoor environments.

5. Top-Access Battery and Precise Adjustments
The top-mounted CR1632 battery compartment allows battery replacement without removing the optic. Windage and elevation adjust at 1 MOA per click, with a total adjustment range of 90 MOA for straightforward and controlled zeroing.

The GOWUTAR A20C gives shooters three selectable red reticle configurations in one compact open reflex sight:
2 MOA Dot: A refined aiming point for precise shot placement.
38 MOA Circle: A bold visual reference designed for rapid target acquisition at closer distances.
2 MOA Dot + 38 MOA Circle: Combines a precise center dot with a fast outer reference for a balanced sight picture.

One Optic for Multiple Platforms

The A20C uses the industry-standard RMR footprint for compatible pistol slides and mounting plates. Its included detachable low-profile Picatinny mount expands the optic’s use to compatible rifles, shotguns, and other Picatinny or Weaver-style rail platforms.
This mounting flexibility makes the A20C suitable for range training, competition, hunting, and general shooting applications across different firearm platforms.

Clear Sight Picture in Changing Light

The fully multi-coated lens helps improve light transmission and reduce reflections for a clear sight picture across different environments. Its 24 × 17.21 mm viewing area provides useful peripheral visibility without adding unnecessary bulk.
Ten brightness settings include eight daylight levels and two night-vision-compatible levels. Adjust the brightness to suit the surrounding conditions and minimize blooming or reticle distortion.

Motion-Activated Readiness

Once switched on, the A20C’s motion-sensing function operates automatically. After approximately four minutes without movement, the reticle turns off to conserve battery power.
When movement is detected, the optic immediately reactivates at the previously selected brightness setting. This provides a practical balance between readiness and efficient power management during storage, transport, and regular use.

Built for Recoil and Harsh Conditions

The A20C housing is machined from 7075 aircraft-grade aluminum for increased strength and durability. Its IPX8 waterproof rating helps protect the internal system from rain and moisture, while its 1800G shock resistance supports reliable performance under repeated recoil and impact.
A hardcoat anodized finish adds surface protection against everyday wear and corrosion.

Convenient Top-Loading Battery

The top-access CR1632 battery compartment allows the battery to be replaced without removing the optic from its mounting position. This simplifies maintenance and helps avoid unnecessary disturbance to the established zero.
Battery life ranges from approximately 160 to 40,000 hours depending on the selected reticle, brightness level, movement, and usage conditions.

Precise Windage and Elevation Control

Windage and elevation adjustments move in 1 MOA increments and provide a total adjustment range of 90 MOA. Audible and tactile clicks help shooters make controlled corrections when zeroing.
The optic is factory preset at approximately 33 yards, but final zero confirmation is still required after installation.

FAQ

What reticles are available on the A20C?

The A20C offers three selectable red reticles: a 2 MOA dot, a 38 MOA circle, and a combined 2 MOA dot with a 38 MOA circle.

How do I change the reticle?

Turn on the optic and hold the ▲ button for three seconds. Repeat this operation to cycle through the three reticle options.

Does changing the reticle affect the zero?

The reticle patterns share the same optical center. Switching between the available reticles is designed to retain the established point of aim, although users should always confirm zero before use.

Does the A20C fit every RMR-cut pistol?

The A20C uses the standard RMR footprint, but slide cuts, adapter plates, mounting depths, and screw requirements can vary. Confirm compatibility with the firearm or plate manufacturer.

Can it be mounted on a rifle or shotgun?

Yes. The included low-profile Picatinny mount allows installation on compatible Picatinny and many Weaver-style rail systems.

Does the A20C have Shake Awake?

Yes. After approximately four minutes without movement, the reticle automatically turns off. Movement reactivates the optic at its previous brightness setting.

Can the battery be changed without removing the optic?

Yes. The top-access battery compartment allows the CR1632 battery to be replaced without removing the sight.

Is the A20C waterproof?

The A20C carries an IPX8 waterproof rating. Make sure the battery cap is correctly installed before exposing the optic to wet conditions.
