KNINE OUTDOORS 2 MOA 20mm Red Dot Sight
$119.99 price checked August 2026
If you need a 2 MOA optic that aligns perfectly with a 3X magnifier, this is the right choice.
KNINE 2 MOA Sight Overview
The KNINE OUTDOORS 2 MOA 20mm Red Dot Sight is for the practical shooter who needs a 2 MOA dot for precise target acquisition at distance.
Misaligned sights or a dot that shifts during recoil can compromise your accuracy and force you to compensate for errors in the field. Precise alignment between your primary optic and your magnification is necessary to ensure the point of aim remains consistent regardless of the power level.
The KNINE OUTDOORS 2 MOA 20mm Red Dot Sight solves this by featuring a magnifier and red dot aligned without height difference. This specific design ensures that your point of aim remains consistent when switching between the 3X magnifier and the base optic.
We selected this model from the red dot sight options we evaluated for this category. This review is for the buyer who prioritizes optical alignment and consistent reticle height for multi-use applications.

The Short Answer on the KNINE 2 MOA Sight

The KNINE 2 MOA Sight is a practical choice at $119.99.
- Pro: The 3X magnifier and red dot are aligned without height difference for consistent target acquisition.
- Pro: It features 10 brightness settings to ensure visibility in various lighting conditions.

Before You Buy: KNINE 2 MOA Sight Checklist
The first thing to check is whether your mounting height allows for 1/3 cowitness, as this optic is designed specifically for that configuration.
- ☐ Verify height compatibility — 1/3 cowitness mounting height
- ☐ Confirm reticle size — 2 MOA red dot sight
- ☐ Check eye relief requirements — 2.4 inches
- ☐ Measure field of view requirements — 49 ft/100 yards
- ☐ Confirm magnifier compatibility — 3X magnifier aligned without height difference
- ☐ Check brightness options — 10 red dot brightness settings
You should not buy the KNINE 2 MOA Sight if your setup requires a high-profile mount that would prevent the red dot center from sitting 1/3 inch higher than your iron sight center.

What These Specifications Let You Do
Magnifier Alignment and Compatibility
The KNINE OUTDOORS 2 MOA 20mm Red Dot Sight features a 3X magnifier that is aligned with the red dot without any height difference. This alignment ensures that your point of aim remains consistent when switching between the 2 MOA red dot and the magnified view. You can transition between optics without needing to adjust for a height offset, which is a common issue in many reflex red dot configurations.
The KNINE 2 MOA Sight is designed for lower 1/3 cowitness mounting heights. This specific design allows the red dot center to sit 1/3 inch higher than the iron sight center. You should verify that your specific firearm’s iron sight height is compatible with a 1/3 cowitness setup to ensure proper alignment during operation.
Optical Clarity and Field of View
Optical clarity on the KNINE 2 MOA Sight is supported by a K9 grade optical lens. The 2 MOA red dot provides a field of view of 49 ft at 100 yards. This field of view allows you to maintain situational awareness while keeping the reticle centered on your target. The 2.4 inches of eye relief distance provides a specific window for proper eye placement to maintain a clear image.
Regarding the dot visibility in direct sunlight, the technical specifications do not provide a specific lumen output or brightness rating for the lowest of the 10 brightness settings. You should check the manufacturer’s specific brightness levels for the lowest setting to determine if the dot remains visible in high-glare environments.
Weatherproof and Shock Resistant Build
The KNINE 2 MOA Sight is built to be weatherproof, fog-proof, and shock-resistant. These specifications indicate the optic can withstand moisture and rapid temperature changes that cause lens fogging. The nitrogen purged magnifier and its secure seal further protect the internal components from environmental ingress during outdoor use.
The shock-resistant construction of the KNINE 2 MOA Sight supports use in high-recoil environments. Because the optic is designed to withstand physical impacts, you can rely on the internal alignment of the 2 MOA red dot and the 3X magnifier remaining stable under heavy vibration. Confirm the local regulations for your specific location before ordering this optic.
