RMSc Footprint Compatible

Osight S - Newest
This is the brand new Osight S model with multiple reticle systems and its fully weatherproof against water and mud.
The optic comes with built in iron sights that perfect go well with guns that have no rear sights after the optic plate removal. For example, the Sig P365XL.
The USB recharging capability is the main feature of this optic that allows the optic to be charged without any battery swap.
Holosun 507K - Best Overall
The Holosun HS507K X2 micro red dot sight stands out as the most favored RMSc red dot sight for subcompact firearms such as the Sig P365 and Shadow System CR920, among others. This compact version mirrors the beloved Holosun 507C X2 while retaining all its cherished features.
Fast Red Dot Target Acquisition - Many shooters including me who wants to master proper shooting techniques can swiftly and accurately acquire the reticle.
Smoother Holster Draw - I've noticed its petite profile ensures a smooth holster draw for me. This means my gun slides in and out of the holster without any snags or hitches, making it really convenient and quick to use.
Innovative ShakeAwake Technology - With the innovative ShakeAwake Technology. The built-in motion sensor triggers the red dot reticle. This is great because it helps preserve the battery life of my CR1632 battery by turning it off when I'm not using it.
Convenient Side Battery Access - I find the side battery access really convenient. It allows me to easily access the battery from the side, which means I don't have to remove the sight or re-zero it. This saves me a lot of time and hassle.

Holosun EPS Carry - Fully Enclosed Body
The Holosun EPS reminds me a lot of the Holosun 509T, but it's smaller and designed with a K mounting footprint.
It also works with an RMSc adapter mounting plate. I also like that this optic is made from durable 7075 T6 aluminum, and I can get it with or without a solar panel, which is pretty cool.
Note: You must use the RMSc adapter plate footprint (Holosun K footprint has a different footprint than RMSc)
Mount on RMSc Footprint - No special pic mount required
Dirt Proof - I have tested this in snow by dropping the gun into a puddle. No water, snow, wet mud or dust can get into the optic's internals
Great For CCW - The similar size as 507K, and it's now fully enclosed
Built In Rear Sight - Provides backup aiming if the optic unit completely replaces rear iron sight ( Sig P365XL red dot)
Cyelee CAT Pro - Best For The Money
I'm really impressed with the Cyelee CAT Pro. This optic may look like a check Chinese knock off because its packaging, but the sight is pretty good for just some range use. And if that's all you need and you don't care, then this one has been nothing short of amazing.
You can mount the CAT PRO effortlessly on optics ready RMSc slides or mounts that fit Shield RMSc, 407k/507k, or JPoint footprints.
Beyond aesthetics, It has increased that thicker window frame to handle drops and impacts.
The optics deck has been slimmed down, and the rear iron sights reworked, now offering better compatibility with standard pistol front iron sights.

Sig Romeo Zero Elite - Best Technology
I've been really impressed with the Sig Romeo Zero Elite, i think it's a bit niche and all you do is with a finger to top the top of the frame to change reticle brightness. Especially for people with larger hands. All you have to do is tap the lens hood.
What's even better is that they've upgraded to a glass aspheric lens instead of polymer in the ROMEO ZERO ELITE, making it much sturdier.
In a nutshell, the Sig Romeo Zero Elite is a "trial optic". No matter how good it is , it's made with polymer and its not for serious use, but it's something cheap to try before you get into something a bit more expensive.
Swampfox Sentinel II - Best Value
The Swampfox Sentinel II is the one you want to get. Forget the first model they came up with many many years ago, like before 2020. The Sentinel II has thicker glass frame and much better machining. the overall body is just nicer.
and it comes with the 6 MOA dot which the older one doesn't have. 6 MOA is great for people with astigmatism.
Also the portable iron sights works great for the P365XL after you remove the optic plate.
I only recommend the Shield RMSc if you want that big 8 MOA dot. The optic itself is just overpriced and many features aren't that much different than other optics on the market.
The auto-adjusting brightness works effectively for various scenarios and co-witnesses naturally with iron sights. While lacking manual adjustment may concern some, it's generally acceptable.
The Riton MPRD (#019962531262) is another budget option RMSc red dot.
At this price range, I don't expect the red dot to be better than a RMRcc or EPS Carry, but for people with big hands, the side buttons that are easier to adjust, especially for individuals with large fingers or those wearing gloves.
The sight comes with a 12-hour auto-shutoff function, offers 10 brightness levels for reticle adjustment, and is compatible with night vision at levels 1-2.
