German Precision Optics (Gpo) Spectra Pistol Reflex 1X3 Moa Dot Motion 1''

The German Precision Optics Spectra Pistol Reflex is a compact 1x3 MOA red dot sight built for shooters who need fast target acquisition without the bulk of magnified optics. Whether you're running a competition pistol, defensive handgun, or rimfire for plinking, this reflex sight delivers a crisp illuminated dot and motion-activated power management to keep you on target when it counts.

GPO engineered the Spectra with high-density polymer lenses and GPObright lens coatings to cut glare and preserve sight picture clarity in variable light. The 3 MOA dot is forgiving enough for close-quarters work while precise enough for deliberate shooting. Tactile 1 MOA click adjustments let you dial in your zero without tools or guesswork. A side-mounted CR 1632 lithium battery powers the sight, and the built-in motion sensor wakes the optic when you move and puts it to sleep during downtime—stretching battery life for extended range sessions or duty use.

The automatic illumination photo sensor adjusts brightness to match your surroundings, so the dot stays visible whether you're shooting indoors under fluorescents or outside in bright sun. The high-efficiency LED holds its consistency shot after shot, which matters when precision and speed both matter. At 1 inch in height, it's designed to mount on modern pistol slides and duck under most holsters and accessories.

Frequently Asked Questions

What pistol or firearm is this reflex sight designed for?

The Spectra Pistol Reflex is engineered for pistol slides that accept reflex sights. Check your pistol's documentation or manual to confirm compatibility. Most modern competition and defensive pistols can be fitted with a pistol reflex sight, but installation and zeroing should be done by someone experienced with your specific firearm.

How long does the battery last?

The motion sensor and auto-off feature significantly extend battery life by powering down the sight during inactivity. Actual runtime depends on how much you use the sight and the brightness level. The included CR 1632 lithium battery is standard; a fresh battery should provide many hours of active use. Check the manual for specific battery life estimates.

Can I adjust the brightness manually, or is it automatic only?

The Spectra includes an automatic illumination photo sensor that adjusts brightness based on ambient light. This ensures the dot stays visible in low light or bright sun without manual intervention.

What does the 3 MOA dot mean, and how does it compare to the 1 MOA adjustments?

The 3 MOA dot is the size of the reticle itself—larger dots are faster to pick up in dynamic shooting but cover more target at distance. The 1 MOA click adjustments refer to the precision of your windage and elevation corrections, allowing you to dial in your zero in small, predictable increments.
