Delta Optical MiniDot III 3 MOA Red Dot Sight with Integrated Picatinny Mount
Ultra-light, rugged and ready to go — the Delta Optical MiniDot III 3 MOA puts a fast, crisp aiming point right where you need it. Its compact profile and built-in Picatinny mount make it ideal for pistols, shotguns and rifles used in dynamic field environments.
Delta Optical MiniDot III is a new, improved generation of the compact MiniDot II open red dot that allows you to quickly and precisely target a moving target. Equipped with a sensor to automatically adjust the intensity of the aiming point, so that the marker always has the appropriate brightness adapted to the surroundings.
The collimator is perfect for hunters on group hunts, as well as for sports shooters in dynamic shooting.
-
3 MOA Red Dot:
A small, precise aiming point that’s fast to pick up without obscuring your target — ideal for quick shots out to moderate distances. -
1× Magnification with Unlimited Eye Relief:
Natural target acquisition with both-eyes-open shooting and no eye-relief limitations. -
Compact & Ultra-Light (≈35 g / 51.7×30×29 mm):
Minimises weight and bulk on pistols or lightweight rifles. -
Integrated Picatinny Mount:
Ready to fit directly onto any 22 mm Picatinny/Weaver rail — no separate plates required. -
Manual & Automatic Brightness:
Dot intensity can be set manually or adjusts automatically to ambient light. -
±120 MOA Windage & Elevation Adjustment:
Fine adjustment range for aligning zero precisely to your firearm. -
Magnesium Alloy Housing:
Durable yet lightweight construction resists impact and environmental exposure. -
Waterproof & Weather-Resistant:
Sealed bottom and robust design help keep internals protected in rain and humidity. -
Long Battery Life (CR1632):
Easy top-access battery replacement with a long service life — no need to remove the sight to change the battery. -
Made in China (brand designed in Poland)
Perfect for:
-
Dynamic shooters — quick engagements, reactive scenarios and target transitions.
-
Hunting setups (shotguns and rifles) where a fast, unobstructed aiming point is key.
-
Pistol platforms with integrated rail cuts or low-profile mounts.
-
Backup/secondary optics — lightweight and compact for secondary mounts or above-optic positions.
Less ideal if:
-
You prefer multiple dot sizes for different engagement ranges (consider a MultiDot model).
-
Extremely long-range precision is your priority — red dots excel in close/medium distances.

Q: What does 3 MOA mean in real use?
A 3 MOA dot roughly subtends ~9 cm at 100 m — small enough for precise aiming at moderate distances while still easy to pick up quickly at close range.
Q: Does this have parallax?
No — like most reflex sights with 1× magnification, it’s parallax-free at typical engagement distances.
Q: What’s included for mounting?
It comes with an integrated Picatinny rail mount ready for standard 22 mm rails
Q: How is the brightness controlled?
You can manually select brightness levels, or let the automatic sensor adapt the dot brightness to ambient light.
Q: How long does the battery last?
Powered by a CR1632 battery, it typically offers long run times before replacement — and the battery is accessed from the top without removing the sight.
Q: Is it waterproof / field-rugged?
Yes — sealed construction and weather-resistant design mean it handles rain, humidity and recoil from pistols and rifles.
