What to Look for in a Holosun Red Dot with Picatinny Mount
Considering a Holosun red dot sight compatible with Picatinny, one has to know the main performance influencing points that can influence the durability, user experience, and functionality of the sight. These are what to remember:
Reticle Options (MRS, Dot Sizes)
Holosun offers a state-of-the-art Multi-Reticle System (MRS) that allows you to switch between various reticle styles, including 2 MOA dots, 32 or 65 MOA circles, and combos.
- Smaller dots (2 MOA) are more accurate at shooting.
- Bigger dots (6=8 MOA) or circle-dots combination also make sense when trying to engage a target at close range quickly.
Go with what works out to your shooting needs, defense, duty, or competition, etcetera.
Power Saving and Battery Life
One of Holosun’s red dots touts a battery life of up to 50,000 hours on a single battery CR1632 or CR2032. There are two proprietary technologies to assist in energy conservation:
- Shake Awake: Automatically turns on when something is moved.
- Solar Failsafe: The optic has a built-in solar panel that can run in bright light (even with no battery).
All these make Holosun optics extremely dependable over a prolonged duration.
Build Quality: Aluminum vs Titanium
The topic of construction material:
- 7075-T6 Aluminum is light, robust, and almost all Holosun models are made with it.
- Titanium (as in the 509T) is even more durable, more impact resistant than T92, and completely geared towards hard-use or duty gear.
Compatibility Mounting ( Picatinny, RMR, RMSc, ACRO )
Picatinny mount. Not every Holosun red dot comes to the box as such; some are designed for pistol slide footprints, like:
- RMR (Trijicon footprint)
- RMSc (Shield footprint)
- ACRO (Aimpoint footprint)
Do Holosun Red Dots Come with a Picatinny Mount?
Yes, but not all models include a Picatinny mount out of the box. Holosun offers a variety of red dot sights, and their mounting systems depend on the intended use (rifle vs pistol) and footprint design (RMR, RMSc, ACRO, etc.).
Models That Include a Picatinny Mount:
- Holosun 510C: Comes with an integrated QD Picatinny mount, making it plug-and-play for rifles, PCCs, and tactical shotguns.
- Holosun 509T: Includes a Picatinny adapter out of the box, even though it uses the ACRO footprint.
Models That Require a Picatinny Adapter:
- Holosun 507C X2: Uses the RMR footprint, so you’ll need an RMR-to-Picatinny adapter for use on rails.
- Holosun 507Comp: Also uses the RMR footprint, designed primarily for slide-mounting, but works great with the right adapter.
- Holosun 407K X2: Built with the Shield RMSc footprint, you’ll need a Picatinny adapter or riser plate for rifle or offset mounting.

Holosun Red Dot with Picatinny Mount
1)Holosun 509T
The Holosun 509T is an elite-level micro red dot sight designed to deliver shooters the ultimate level of durability, reliability, and advanced capabilities.
Its design of a closed emitter is what makes it different as compared to open-type red dots, and this type of design makes it well suited to being used in adverse weather conditions as rain, snow, or dust areas. The 509T is made of titanium, which is strong and lightweight.
Among its most publicized attributes is its Multi-Reticle System (MRS) technology that provides the ability to switch among a 2 MOA dot, a 32 MOA ring, or a combination of both of these reticles-increasing versatility about speed of target acquisition or accuracy.
Also has Shake Awake, Solar Power Failsafe, and a staggering 50,000 hours battery life with a side-loading battery of CR1632.
Come with a Picatinny mount already installed on it, and hence is viable to be mounted on rifles, shotguns, and even medium-sized pistols. It is also interchangeable with the ACRO footprint, making it multipurpose.
Key specs
- Reticle: 2 MOA dot, 32 MOA circle, or both (MRS)
- Emitter Type: Fully enclosed

One of the most popular and the most versatile red dot sights, allowing it to be mounted on rifles, PCCs, and tactical shotguns, is the Holosun 510C.
It also has a great open reflex design and an inbuilt QD Picatinny mount, and thus, when mounted on the majority of guns with a standard rail, it is so easy to mount and zero.
Taking this gun to the range, on your way to settling a home invasion, or preparing to shoot for an event, you will have the assurance of performance that is rock solid.
The significant aspect is the Multi-Reticle System (MRS) of Holosun, which allows the shooter to select either the 2 MOA dot or the 65 MOA ring, and also the combination of both.
This is made to be generic, allowing targets to be visited at varying distances at varying speeds. It consists of an alloy titanium hood, which has an aluminium body that provides exceptional durability, yet not excessive bulkiness.
Comes with Solar Failsafe, too, so that your optic is in operation even when your battery fades in the middle of your hunting session, and Shake Awake to save the breathtaking 50,000-hour battery life on a single CR2032 battery.

The 507Comp is an advantage you need whether you are shooting a USPSA match or practicing fast-paced drills.
This red dot sight applies the new CRS (Competition Reticle System) by Holosun, and the user can easily switch between the dot size of 2 MOA, circle size of 8 MOA, circle size of 20 MOA, or full-size reticle combo. That adjustability allows the shooters to optimize the sight picture to enhance speed or accuracy, or both.
Its RMR footprint allows the RMR to be compatible with most pistol slides that are optic-ready and Picatinny adapters, and the side-loading CR1632 battery is rated to 50,000 hours of continued operation. Together with the Shake Awake and Solar Failsafe, the 507Comp is in standby when you are.
It was originally intended to be used on pistols, but it shines when attached to a Picatinny rail on offset mounts on rifles or PCCs, or other large-frame pistols.

Designed on the popular RMR footprint, it can be attached to almost any pistol and rifle, regardless of whether it has a Picatinny adapter or not.
It is an optic that has the tried and true Holosun Multi-Reticle System (MRS) that gives the shooter a choice of using a 2 MOA dot, a 32 MOA ring, or both. The 507C X2 has precision or speed covered, whichever you want: a clean dot or a circle-dot combination.
Longevity is also a good attribute. The housing is made of 7075-T6 aluminum and has resistance to recoil and harsh weather. There is also the Shake Awake technology and Solar Failsafe that keeps the sight ready at all times, saving battery when a user is not using it, and the sight automatically adjusts its brightness in ambient light.
Its side-load CR1632 battery has a usage of up to 50,000 hours, thus you will not be swapping batteries frequently. With a good Picatinny adapter, the 507C X2 turns into a very stable carbine, shotgun, or offset rifle mount.

It has an ultra-lightweight design and is small with a compact Shield RMSc footprint so it is an ideal fit with micro-compact pistols but due to having the capability of attaching a compatible adapter to Picatinny rails it is a surprisingly versatile solution in terms of being able to mount to ultra-light carbines or for using an offset design.
Has a clear 6 MOA red dot, which is bigger than the usual amount of 2 MOA, rendering this optic to be readily discernible in the most extreme conditions, notably in the short sight radius of small weapons.
Made of 7075-T6 aluminum, the 407K X2 can handle all the abuse you can reasonably subject it to daily, whether loading it up to be carried all the time or abusing it at the range, without being a heavy part of your equipment.
Like other Holosun optics, it has Shake Awake, uses a side-loading CR1632 battery, and provides up to 50,000 hours of run time.

FAQs
- Do all Holosun red dot models include a Picatinny mount?
No, not all models. Some, like the 510C or 509T, come with integrated Picatinny mounts. Others, especially pistol-optimized models such as the 507C X2, 507Comp, or 407K X2, use RMR or Shield RMSc footprints and require separate RMR-to-Picatinny adapters.
- How can I mount a pistol-style Holosun optic on a rifle with a Picatinny rail?
You’ll need an adapter plate. For example, the RMR-to-Picatinny OLED-style adapter fits lids like the 507C X2 or 507Comp into a rifle or carbine Picatinny rail. Ensure the adapter is compatible with your travel setup and doesn’t interfere with your optic’s clearance.
- Are there Picatinny-mount Holosun models for pistols?
No standard pistol-mounted Holosun red dots include Picatinny rails in the body. Instead, they use slide footprints like:
- RMR
- Shield RMSc
- ACRO
