Product Features

One Optic. Multiple Platforms. Dependable Performance.

The GOWUTAR A20R combines an industry-standard RMR footprint with an included low-profile Picatinny mount, allowing the optic to be configured for compatible pistols, rifles, and shotguns. Its crisp 2 MOA red dot, 24 × 17.21 mm viewing window, motion-activated illumination, and rugged 7075 aluminum housing deliver dependable performance for range training, competition, hunting, and everyday use.

1. RMR Footprint with Included Picatinny Mount
Mount the A20R directly to a compatible RMR-cut slide or mounting plate. The included low-profile Picatinny mount also expands its use to compatible rifles, shotguns, and other Picatinny or Weaver-style rail platforms.

2. Crisp 2 MOA Red Dot
The precise 2 MOA red dot provides a clean aiming point for accurate shots while remaining easy to acquire during faster shooting. Ten brightness settings—including eight daylight and two night-vision-compatible levels—help maintain visibility across changing light conditions.

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

4. Rugged 7075 Aluminum Construction
The housing is constructed from 7075 aircraft-grade aluminum and rated for 1800G shock resistance and IPX8 waterproof protection. It is engineered to withstand recoil, rain, moisture, and demanding outdoor conditions while maintaining a dependable zero.

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

Precise 2 MOA Red Dot

A 2 MOA red dot provides a refined aiming point that supports accurate shooting without unnecessarily covering the target. The fully multi-coated lens helps improve light transmission and reduce distracting reflections, while the 24 × 17.21 mm viewing area offers a clear and practical sight picture.

With unlimited eye relief and 1× magnification, the A20R supports fast, both-eyes-open aiming and improved awareness of the surrounding area.

GOWUTAR A20R RMR red dot sight featuring Shake Awake technologyMotion-Activated Readiness

Once the optic is switched on, its motion-sensing function operates automatically. After approximately four minutes without movement, the reticle turns off to conserve battery power. When the optic detects movement, the reticle immediately returns at the previously selected brightness setting.

This feature helps balance instant readiness with efficient battery use during storage, transport, range sessions, and everyday use.
