None of the five listed sights has a 10 MOA reticle: their specified dot sizes are 2, 3, or 6 MOA, and one model offers a circle-dot option. If you specifically need a 10 MOA dot, verify the reticle specification before buying. Among these alternatives, the ohhunt RD U1 and Triton Nautilus2 are 3 MOA choices for compact pistol setups, the HOLOSUN offers a 2 MOA dot for a full-size pistol, and the OSIGHT SE provides a larger 6 MOA dot in an enclosed design.
| Product | Listed reticle | Best suited for |
|---|---|---|
| ohhunt RD U1 | 3 MOA | RMSc-footprint buyers seeking motion activation |
| Triton Nautilus2 | 3 MOA | Buyers wanting integrated rear sights |
| HOLOSUN 407C/507C-X2 series | 2 MOA dot; circle-dot option listed | Full-size pistol applications |
| MidTen 2 MOA | 2 MOA | Buyers seeking a tube-style sight with a riser mount |
| OSIGHT SE | 6 MOA dot or multi-reticle options | Buyers preferring an enclosed optic and larger dot |
ohhunt RD U1 3 MOA Red Dot

The ohhunt RD U1 is a 3 MOA micro red dot with an RMSc footprint and Picatinny mount. Its listed features include Shake Awake, 10 illumination settings, and two low settings intended for night-vision use. The manufacturer states battery life varies by brightness, listing up to 50,000 hours on a low setting and 2,000 hours at the highest setting.
Best for: Buyers looking for a compact 3 MOA option with motion-activated wake-up and multiple brightness levels. It is included as a smaller-dot alternative, not as a 10 MOA sight. Limitation: Its specified dot is 3 MOA, so it does not meet a 10 MOA requirement; confirm the mount and firearm fit before purchase.
Triton Nautilus2 With Integrated Rear Sights

This pistol optic has a listed 3 MOA red dot and rear iron sights built into the housing. The product information specifies an RMSc/407K/507K footprint, Shake Awake, 10 brightness settings, and a stated 50,000-hour battery life. The listing says it mounts directly to compatible RMSc-cut slides without an adapter; check the specific slide and mounting instructions rather than assuming fit.
Best for: Buyers who want a compact 3 MOA optic with backup rear sights incorporated into the body. That combination distinguishes it from the other listed compact options. Limitation: The dot is 3 MOA, not 10 MOA, and the sight is described for compatible pistol cuts rather than universal mounting.
HOLOSUN 407C/507C-X2 Series

The listed series includes a 2 MOA dot and a 32 MOA circle-dot option. The HS407C X2 is described as an open reflex sight for full-size pistols, with a 7075 aluminum housing, side-loading battery tray, Solar Failsafe, Shake Awake, and Lock Mode. The listing gives a battery life of up to 50,000 hours and identifies an RMR footprint.
Best for: Buyers who prefer a fine 2 MOA dot or want to compare it with the series’ circle-dot configuration. It offers more reticle context than a single-dot listing. Limitation: Neither the 2 MOA dot nor the 32 MOA circle is a 10 MOA dot; verify the exact model and reticle selected.
MidTen 2 MOA Tube-Style Red Dot

The MidTen is a 1×25 mm tube-style reflex sight with a 2 MOA dot and a 1-inch riser mount. Its feature list cites unlimited eye relief, a multi-coated scratch-resistant lens, and 11 brightness settings. The listed brightness guidance separates dim or rainy conditions from bright daylight settings.
Best for: Buyers comparing a tube-style sight with a smaller 2 MOA dot and included riser mount. Its format differs from the compact pistol optics above. Limitation: The dot is 2 MOA, not 10 MOA, and the supplied information does not establish compatibility with a particular firearm or mounting setup.
OSIGHT SE Enclosed Red/Green Dot

The OSIGHT SE is an enclosed-emitter optic offered with a 6 MOA dot or listed multi-reticle options. Its product information identifies an RMSc footprint and says non-RMSc slides require an adapter plate that is not included. The listing describes the larger dot as intended to support quick acquisition and easier alignment during movement.
Best for: Buyers who prefer a larger listed dot than the 2 or 3 MOA alternatives and want an enclosed optic. It is the closest listed choice in dot size to a 10 MOA target, but it is still 6 MOA. Limitation: An adapter may be needed for a non-RMSc slide, and it is not a 10 MOA sight.
Buying Guide: How to Choose a Red Dot
Does this sight actually have a 10 MOA dot?
Check the exact reticle specification, not just the product title or general description. MOA describes angular dot size: a larger MOA dot appears larger on the target, while a smaller one can cover less of it. The products here specify 2, 3, or 6 MOA dots, plus a 32 MOA circle option. None specifies a 10 MOA dot.
Which dot size should you compare?
A 2 MOA dot is the smallest listed choice here and may suit buyers who prefer a more precise-looking aiming point. The 3 MOA models offer an intermediate dot size. The OSIGHT SE’s 6 MOA option is the largest specified dot among these products and may be easier to see quickly for some users. These descriptions do not make any of them equivalent to 10 MOA.
Will the optic fit your firearm?
Match the optic footprint to the slide or mounting platform. RMSc, 407K/507K, RMR, and Picatinny are different mounting specifications. Confirm the firearm’s cut and whether an adapter or separate mount is required. Do not assume that a footprint listed for one model in a series applies to every product or variant.
What features matter beyond dot size?
Compare brightness controls, battery access, motion activation, reticle choices, and housing style. Shake Awake or similar motion activation appears on several listed models, while the MidTen lists 11 brightness levels. The OSIGHT SE is described as enclosed; several others are open designs. Choose based on the feature you need, and verify manufacturer instructions for operation and maintenance.

Which listed optic has the largest dot?
The OSIGHT SE lists a 6 MOA dot, the largest specified dot among these five products.
Is a 32 MOA circle the same as a 10 MOA dot?
No. A 32 MOA circle is a different reticle feature and should not be treated as a 10 MOA dot.
Do all the products fit the same pistol cut?
No. The listings name different footprints and mounting arrangements. Check the exact optic and firearm specifications before purchase.
