Top 7 Red Dot Sights That Fit RMSc Footprint

Holosun 507K - Best Overall

The Holosun HS507K X2 micro red dot sight is the most popular RMSc red dot sight for subcompact guns like Sig P365, Shadow System CR920 and many others. The light is a smaller version of the popular Holosun 507C X2 without compromising all the features people already love.

Fast Target Red Dot Acquisition - Shooters who apply proper shooting fundamentals can pick up the reticle extremely fast and accurate

Snag free holster draw - Its small size profile makes the gun go in and out of the holster without getting caught on stuff

ShakeAwake Technology - Motion sensor activates the red dot reticle, and it turns off while in ideal to save more battery juice (CR1632 battery)

Side Battery Access - Accessing battery from the side. No sight removal or re-zeroing required

Holosun EPS Carry - Fully Enclosed Body

Holosun EPS is like the Holosun 509T, but smaller and it features a RMSc mounting footprint. Users can directly mount this on RMSc footprint handgun slides without any special adapter plates.

The optic is built with 7075 T6 aluminum, and it either comes with solar panel or without.

Note: Both EPS and EPS Carry feature RMSc footprint (aka K footprint branded by Holosun)

Mount on RMSc Footprint - No special pic mount required 

Dirt Proof - 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 (like the Sig P365XL)

Sig Romeo Zero Elite - Best For Big Hands

Sig Romeo Zero Elite is upgraded with a finger TAP operated circuit system.

This means a person with large hand can simply tap the hood of the lens to adjust the reticle brightness.

The newest upgrades the ROMEO ZERO ELITE features is a glass aspheric lens instead of polymer for a stronger build.

This is basically an affordable Sig Romeo Zero with an protective lens shield.

Swampfox Sentinel - Best For The Money

The Swampfox Sentinel is another one of the top selling red dots. For any Springfield Hellcat owners, this optic will fit directly on the Hellcat OSP slide without any index post filing.

Minimal View Obstruction - Aim with both eyes open without thick lens frame getting in the way 

Durable 7075 Body - Hard coated aluminum body to withstand charging the slide against belt or hard surfaces

Add Extra Protection - Mount IRONSLIDES SHIELD (sold separately) to beef up the lens hood from barricade racking, drop and other physical impact

Auto or Manual - Two optic options are available, Auto model is ambient light activated.

Springfield Armory WASP - For Beginner Use

The Springfield Armory Hex WASP micro red dot sight features the RMSc footprint. The entire optic weighs only 0.7 oz, and it's a much nicer product than the Swampfox Sentinel with a much better external body design.

Serrated Optic Body - Optic serration helps the user to grip the optic as a part of the slide to rack it

Thick Lens Frame - Withstand slide racking against hard surfaces like an RMRcc, and the built in rear iron sight is just like the Holosun 507K

Finer MOA Dot Adjustment - The WASP features a 0.5 MOA / Click for finer adjustment to be more accurate when zeroing the optic

Automatic brightness adjustment - The light sensor detects ambient light sources around and adjust the brightness to suit indoor and outdoor use without having to touch any buttons

shield rmsc reflex red dot sight

The Shield RMSc is the original RMSc optic with skeletonized lens frame, but it's super sturdy. However, the Shield RMSc is a bit too expensive for what it can do.

The Riton MPRD (#019962531262) has been on the market for a while, and it's a awesome RMSc red dot sight for guns like Glock 43X MOS, Springfield Hellcat, TP9 and Shadow System CR920.

The overall red dot sight quality is slightly beefier than the Swampfox Sentinel (but not 7075 T6 body), and the side buttons are easier to adjust for people with big fingers or wearing gloves.

The sight features a 12 hr auto shut off, 10 brightness level reticle adjustment, and it's compatible with night vision on level 1 - 2. 


Is RMSc Footprint The Same As RMRcc?

No. RMRcc footprint is not the same as RMSc. They are two different footprint designs.
