Top 5 Holosun Optics for the S&W M&P 5.7 (No Adapter Plate Needed)

Best Optics for S&W M&P 5.7

IMPORTANT: If you are mounting a Holosun 407K/507K to your M&P 5.7 you will need to get #6-32x1/2 screws get them here. 

We are very happy Smith & Wesson came out with the M&P 5.7. The 5.7 caliber is super awesome, and we love seeing it in affordable pistols.

The other thing we are happy about is that S&W made these pistols optics ready. If you are wondering what the best optics are for the M&P 5.7 then keep reading.

Smith & Wesson M&P 5.7 Optics Footprint

The M&P 5.7 has a modified RMSc footprint. Which means it has two recoil lugs in the front and none in the rear. This means you can mount a Holosun 407K, 507K, or EPS carry on it.

No adapter plate is needed but you will need 6-32x1/2 screws which we sell here. If you purchase any of these optics from us we can include the screws for you at no extra charge, just contact us letting us know you have an M&P 5.7.

The Best Holosun Optics for the S&W M&P 5.7

The red & green dot optics we recommend for the S&W M&P 5.7 are the Holosun 407K, 507K, and the EPS Carry or EPS if you want a little bigger of a window.

We recommend these optics because we believe they are the best bang for your buck.

  • They are affordable but not cheap. 
  • They are built sturdily with strong aluminum housings and glass. 
  • They have convenient features like Shake Awake and Side Mounted Batteries.
  • They have a Limited Lifetime Warranty.
  • They are reliable.

1. Holosun 407K Red & Green Dot


The Holosun 407K is a great optic. It's the most affordable in this list and is jammed with features like shake awake, 7075 aluminum housing, removable side battery and a really nice 6 MOA dot reticle. This is a good size because it's big enough to pick up, but small enough to still be precise.

If your trying to be budget conscious, the 407K is a great choice.

2. Holosun 507K Red & Green Dot

Holosun MRS Toggle

The next optic we recommend for the S&W M&P 5.7 is the Holosun 507K. This comes in red or green reticles and is almost identical to the 407K except is has Holosun's Multi-Reticle System (MRS) which is a 2 MOA dot with a 32 MOA ring. You can toggle the reticle to have just the dot, just the ring, or the ring and the dot by pressing the "-" button for 3 seconds.

The MRS reticle is nice because it gives you some options, and the 32 MOA ring makes picking the reticle up upon drawing a bit easier.

The 507K has all the same features as the 407K but it is a little bit more expensive due to the reticle.

3. Holosun EPS Carry Red & Green Dot

Holosun EPS Carry

The EPS Carry is one of the newest optics released by Holosun. It has an enclosed emitter, which means it has two panes of glass an a hood. This protects the laser beam ensuring nothing can come between the beam and the glass.

This is good for keeping debris, dust, water, lint, dirt, or any other objects out of the line of the laser. We would recommend this for someone who demands the most durability possible.

The EPS Carry can be purchased with three different reticles. Either the MRS, 6 MOA, or 2 MOA. The MRS version also has a solar panel on the top which acts as a solar failsafe and gives the optic auto brightness capabilities.

4. Holosun EPS Full Size Red & Green Dot

Holosun EPS Full Size

Holosun also released the EPS .. which is a slightly larger version of the EPS Carry. It's an enclosed emitter optic and has all the same features and reticles as the EPS carry, except it's made for more full size pistols.

It will still mount directly onto the S&W M&P 5.7. There may be a little bit of overhang on the slide, but you will get a larger window to look through.

If you wanted something a little bigger we would recommend this optic.

It's available in the MRS, 6 MOA, and 2 MOA reticles, and the MRS version has the solar panels.

5. Holosun 507K ACSS Vulcan Green & Red Dot

The 507K ACSS Vulcan is exactly like the 507K except is has the ACSS Vulcan reticle. This reticle has a 230 MOA dotted outer ring and a 3 MOA center dot.

The purpose of this reticle is to help you find the center dot quickly if you are off center. To learn more about the ACSS Vulcan check out our article here.

The dotted outer ring can be turned off by holding down the "-" button for 3 seconds.

The main advantage of the ACSS Vulcan reticle is to be able to find the center dot quickly when drawing the pistol.

All the features are the same as the 507K except for the reticle, and this is available in both red & green.

Choosing between Red or Green Reticles

You may be wondering if you should get a red or green dot reticle. We get this question a lot so I am going to list a few bullet points for you to consider.

  • Green reticles are less straining for the eye to see.
  • Green reticles can help with astigmatism. If you have astigmatism you will see a blurry dot, we have been told by a few customers that Green dots help with their astigmatism, making the dot look more crisp than the red version.
  • Green will not washout on backdrops like green grass, foliage, or green colors.
  • In theory Green dots can have a longer battery life because Green is brighter, so for example a green dot on brightness setting 6 may be the same brightness as a red dot on setting 7 - which would save battery life.

If you want to learn more check out our full article about Red vs Green Dot Pros & Cons here.

Choosing between Open vs Closed Emitters

The simplest way we can break down open vs closed emitters is to look at how you plan on carrying the pistol. If you plan on being outdoors in the elements with rain, snow, sleet, then a closed emitter will be beneficial.

If you plan on carrying OWB most of the time and plan on being outside then closed emitter would be beneficial.

If you plan on carrying IWB or don't plan on being outside using your red dot in the pouring rain or heavy snow then an open reflex is fine.

Open reflexes will still work in the rain or snow but the closed emitter will give you extra peace of mind.

An open reflex can collect dust and debris on the inside of the reticle over time, so you'll want to clean it out from time to time. An enclosed emitter is easier to clean in this aspect.

How to decide which reticle style is best for you

In this guide we covered a few different reticle options. If you need some help deciding which is best for you here are some of our thoughts on each.

  • 2 MOA only (EPS Carry 2 MOA): This dot is quite small which makes it precise. The downside is that it can be hard to “pick up” upon drawing the weapon. If you are experienced shooting red dot sights on pistols then this may not be an issue for you. If you are new, we recommend you practice “finding the dot” at home to become proficient. If you can train your muscle memory to find the dot then 2 MOA is a great choice.
  • 6 MOA only (407KEPS Carry 6 MOA): This dot is decently larger than the 2 MOA dot. We classify this as more user friendly than the 2 MOA dot as it’s a bit easier to pick up upon drawing. The 6 MOA dot will not be as precise as the 2 MOA dot at long distances (50+ yards) but it is still plenty accurate at all distance ranges. The 6 MOA dot is a nice size and it gives you a less cluttered reticle. Some people prefer it over the MRS.
  • MRS Reticle (32 MOA Ring + 2 MOA Dot) (507K, EPS Carry MRS: This reticle is a good combination of both large and small. You have the 2 MOA dot to be precise with, and the 32 MOA Ring to help “find the dot”. The 32 MOA Circle is quite hard to miss. The nice thing about this reticle is the flexibility. You can use the 32 MOA Ring only or the 2 MOA dot only or both together. This way you can find what you prefer and stick to it.
  • ACSS Vulcan with 3 MOA Dot and 230 MOA Dotted Outer Ring (507K ACSS Vulcan): This reticle is going to have a 3 moa dot and the 230 MOA dotted outer ring. The outer ring is only visible when the dot is not centered. The purpose is to help you find the dot quicker upon drawing the weapon. The 3 MOA dot give you a slightly larger dot than the 2 MOA dot, but it’s not that noticeable. The real value to this reticle is the outer ring and it’s assistance with helping you get on target faster by quickly adjusting your grip to “find the dot”


You can't go wrong with any of the red or green dot sights listed in this article. The 407K is great, the 507K is great, and so is the EPS Carry and the EPS. It really comes down to what suits your preferences and also your budget.

We hope you found the article helpful, and if you have any further questions please reach out to us. We are always happy to help!

BIJAL no .. the only ACSS Vulcan reticle that will fit is the 507K ACSS Vulcan which has a 3 MOA Dot and 230 MOA Dotted outer ring.

Will the 509 or 507C with the Chevron reticle thread patterns fit the 5.7 mounting holes?
