Best PSA Dagger Holosun Optics Full Size & Compact (RMR Cut) - Red & Green Dot

If you purchased the Palmetto State Armory Dagger Fullsize or Compact with an RMR cut slide then this article is going to give you the best four optics you could put on it.

We consider them the best because of their reliability, features, price point, and reputation. There are other options out there, but we and many others believe these to be the best.

These all have an RMR footprint, which is a direct fit on your PSA dagger with RMR cut slide. Make sure you use the screws PSA gives you and not the ones that come with these Holosun Optics.

Why do we recommend the Holosun Optics vs other options?

• 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.
• They are waterproof.

1. Holosun 407C and 507C Red & Green

These are the most affordable option and have a great reputation.

The only difference between the 407C and the 507C is the reticle. The 507C has the MRS reticle and the 407C has a 2 MOA Dot.

The MRS reticle stands for multi-reticle system and has a 32 MOA Circle + 2 MOA Dot.

It can be toggled to have only the circle, the circle + dot, or just the dot. You adjust it by holding down the "-" button. 

Highlights:

• Available in Red or Green Reticles
• Available in MRS or 2 MOA Dot
• RMR Footprint
• 7075 T6 Aluminum Housing

2. Holosun 508T Red & Green

This is the next step up from the 507C. It's very similar to the 507C the only difference is the housing is made out of titanium and it has a square shape.

Both the titanium housing and the square shape make this a more durable optic, which means it performs better on drop tests than an aluminum optic or an optic with the rounded top.

Highlights:

• Titanium Housing
• RMR Footprint
• MRS Reticle - Available in red or green
• Shake Awake (Auto on and off)
• Solar Failsafe
• Auto Brightness Mode (can be turned off)
• Removable Side Battery
• IP67 Waterproof Rating
• 50k Hours Battery Life (Setting 6 dot only)
• 10 Daylight Brightness Settings + 2 Nightvision
• 1 MOA click adjustment.

3. Holosun 509T Red & Green

This is the next step up from the 508T. The 509T is an enclosed emitter optic. This means it has two panes of glass and a hood that covers the laser beam.

This is good if you are getting lint or debris inside your optic and have to keep cleaning it out, this eliminates that. It will also keep things like dirt or mud out of the emitter.

Highlights:

• Enclosed Emitter
• Titanium Housing
• RMR Footprint (Clamps to an RMR Plate which is included)
• MRS Reticle - Available in red or green
• Shake Awake (Auto on and off)
• Solar Failsafe
• Auto Brightness Mode (can be turned off)
• Removable Side Battery
• IP67 Waterproof Rating
• 50k Hours Battery Life (Setting 6 dot only)
• 10 Daylight Brightness Settings + 2 Nightvision
• 1 MOA click adjustment.

4. Holosun EPS MRS, 2 MOA, and 6 MOA Red & Green

Last but not least is the Holosun EPS. This is a newer release from Holosun and it's an enclosed emitter optic. It's similar to the 509T but has it's differences.

The main difference from the 509T is that it has more reticle options, is a lower price point, is made out of aluminum and doesn't use the clamp style mounting system.

Highlights:

• Enclosed Emitter
• 7075 T6 Aluminum Housing
• Modified RMSc Footprint (Comes with RMR Adapter Plate)

5. Holosun 507C ACSS Vulcan Red or Green

The 507C ACSS Vulcan is just like the 507C MRS except it has the Primary Arms ACSS Vulcan Reticle. This is a 10 MOA Chevron with a 250 MOA Outer ring.

When you look through the optic all you will see is the chevron. The chevron has a precise aiming point and acts as a BDC reticle. The 250 MOA outer ring is only visible when you do not have your dot centered. The ring is meant to act as a guide helping you find the dot quickly upon drawing the weapon. It’s a pretty cool system!

• Aluminum Housing
• Red or Green Dot ACSS Vulcan Reticle (learn more here)
• 10 MOA Chevron + 250 MOA Outer Ring 
• Up to 20,000 Hours Battery Life 
• 12 Brightness Setting: 10 DL & 2 NV Compatible

It's worth mentioning that the 509T adapter plate we mentioned above will not work with this 509 ACSS Vuclan.

7. Holosun 507 Comp Green & Red Dot - Largest Window Competition Reticle

Buy the 507 Comp At The Best Price

Next on the list is the Holosun 507 Comp. This is one of the newest and most sought after optics from Holosun. Comp stands for "Competition" because this optic features a VERY large window, meant for competition shooting. It's the largest window in the industry.

The 507 Comp has some key differences vs the other optics listed here. First it has the C.R.S. which is the Complete Reticle System. This gives it many reticle configurations like a 2 MOA Dot only or a 2 MOA dot + 8 or 20 or 32 MOA Circle or just a 8 or 20 or 32 MOA Circle.

The 507 Comp also does not have a solar panel on it which means there is also no auto brightness setting.

It has a 7075 aluminum housing, shake awake, a side removable battery, manual brightness modes, 10 daylight and 2 nightvision settings, and is IP67 waterproof.

This is a large optic.

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.

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 (407C, EPS 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 (EPS 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) (507C, 508T, 509T, EPS 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 10 MOA Chevron and 250 MOA Outer Ring (507C ACSS Vulcan, 509 ACSS Vulcan): This reticle is going to be the most precise out of all the other options because of it’s Chevron. The tip of the chevron is the most precise aiming point in any red dot reticle. The 250 MOA outer ring is not visible when the chevron is centered, it’s only visible when you need to adjust your aim. This way “finding the dot” becomes quicker. The chevron also gives you range finding capabilities which none of the other optics do. The only shorter battery life compared to other options.

Conclusion

You can't go wrong with any of these optics. They have a great warranty, are very durable, and have a great reputation. If you have any questions please leave a comment or reach out to us on chat.
