Why do we recommend Holosun Optics vs other options?
Holosun optics offer the perfect balance of quality and affordability. Here are a few key reasons why we recommend them:
- They provide exceptional battery life, and you can change the battery without removing the optic.
- Available in both red and green reticles, with various sizes and styles to suit your preferences.
- Built to last, they feature durable 7075 aluminum or titanium housings and high-quality glass.
- Holosun optics are packed with convenient features like Shake Awake, easy-to-use brightness buttons, and side-mounted batteries for hassle-free maintenance.
- Many models come with solar panels that keep the optic running even if the battery dies.
- They are backed by a Limited Lifetime Warranty.
- Known for their reliability, they are waterproof and have a solid reputation in the industry.
When compared to brands like Leupold, Trijicon, Crimson Trace, Burris, Bushnell, or Aimpoint, Holosun optics often stand out for being more affordable while offering more features, longer battery life, and a proven track record with millions of units sold over the past decade.
What optics footprint is the SAR9?
The SAR9 has a unique footprint but comes from the factory with a modified RMSc footprint adapter plate a.k.a. Holosun K Series. This means all the Holosun K Series optics will fit on the adapter plate. Replacement adapter plates can be found at SAR.
Best Modified RMSc Footprint Holosun Optics for the SAR9
Below are the best Holosun Red & Green dot sights you can mount on your SAR9 Optics Ready version with the included adapter plate.
1. Holosun 407K Green & Red Dot - Best Budget Option
Buy the 407K At The Best Price
This is the most affordable micro optic Holosun makes and is available in a 6 MOA green or red dot.
If you are looking for a single dot optic that is very affordable and great for plinking then this might be the one for you.
The 6 MOA dot is a really nice size. It's big enough to pick up rather easily, but still small enough to be precise with.
It has an aluminum housing, side removable battery, manual brightness controls, shake awake, is IP67 waterproof, and 50,000hrs of battery life.

2. Holosun 507K Green & Red Dot - Best All Around Option
Buy the 507K At The Best Price
The next step up from the 407K is the 507K. This has all the same features like an aluminum housing, side removable battery, manual brightness controls, shake awake, IP67 waterproof, and long battery life but it also has Holosun's Multi Reticle System (MRS).
The MRS Reticle is a 32 MOA Ring with a 2 MOA dot. It's really cool when you look at it - it's similar to an EOtech's reticle if you've ever seen them.
The other cool thing is you can toggle the reticle holding down the "-" for 3 seconds. So if you wanted to, you could use just the 32 MOA Ring, the 2 MOA Dot only, or both the 32 MOA Ring + the 2 MOA Dot.

3. Holosun 507K ACSS Vulcan Green & Red Dot - Best Speciality Option
Buy the 507K ACSS Vulcan At The Best Price
Next on the list is the 507K ACSS Vulcan. This 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 reticle 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.

4. Holosun EPS Carry - Closed Emitter Option - Best Enclosed Emitter Option
Buy the EPS Carry At The Best Price
The EPS Carry is very similar to the 407K and 507K except it has one major difference, it is an enclosed emitter optic. This means the laser emitter is protected by a hood. So dirt, mud, or debris will never get in the way of the emitter to distort the reticle. It also has the highest waterproof rating at IPX8.
There are 3 versions of the EPS Carry. The 2MOA, 6MOA, and MRS Versions
The MRS version has a solar panel on it which acts as a solar fail safe to power the reticle of the battery dies. It also gives you an extra auto brightness feature which can be toggled on or off.

5. Holosun SCS Carry Green Dot - Best Solar Recharging Option
Buy the SCS Carry At The Best Price
The SCS Carry is similar to the EPS Carry in that it is an enclosed emitter, except it features Holosun's latest "Solar Recharging Technology".
It has an internal rechargeable battery with theoretical unlimited battery life. The battery has a 20K hour power reserve which is constantly being recharged. The optic charges the battery faster than it consumes. It has the MRS (multi reticle system) and is available in green dot only. You can use the 2 MOA dot, 2 MOA Dot + 32 MOA Circle, or 32 MOA Circle only.
This model doesn't have Shake Awake like the others, but recommend from Holosun, you just leave it on and it will stay on. It is constantly recharging from natural and artificial light sources. It does have a power off button if you wanted to turn it off.
This optic is a great option if you are looking for something super sleek, and where you never have to worry about batteries. Just turn it on and keep it on!
Choosing between Red or Green Reticles
Deciding on a red or green dot reticle? Here are a few key factors to help make the choice easier:
- Eye Comfort: Green reticles are often gentler on the eyes and cause less strain, making them easier to focus on.
- Astigmatism: If you have astigmatism, a green dot may appear sharper. Many users with astigmatism find that green dots provide a clearer view than red.
- Background Contrast: Despite what some people think, green reticles won’t blend into natural green backgrounds like grass, trees, or foliage Which makes them great for outdoor settings.
- Battery Efficiency: Since green appears brighter to the eye, a green dot at brightness level 6 can look as bright as a red dot at level 7, which can help extend battery life.

Choosing between Open vs Closed Emitters
When deciding between an open or closed emitter for your SAR9, think about how and where you’ll be carrying it.
If you expect to be outdoors in rough conditions—like rain, snow, or sleet—a closed emitter provides extra protection and reliability. For those carrying outside the waistband (OWB) and spending significant time outdoors, the closed design offers added peace of mind in harsh weather.
However, if you typically carry inside the waistband (IWB) and aren’t often exposed to heavy rain or snow, an open emitter can serve you well.
While open emitters hold up in many outdoor environments, closed designs add a layer of durability. It’s also worth noting that open sights may collect dust or debris on the reticle over time, so they’ll need regular cleaning. Closed emitters, on the other hand, are generally easier to maintain in terms of keeping the reticle clear.
