Features in Detail:

Lightweight yet Durable Design:


This reflex sight doesn’t compromise on quality and accuracy. That’s where it beats out other competitors in the same price range!

Housed in an Aluminum frame and titanium hood, it makes it lightweight and durable at the same time. Apart from the titanium hood, 510C focuses on rough shooting. Hence, it yields an MAO, i.e., Micro Arc Oxidation on the lens’s surface for a reinforced feel and longer run. No need to invest multiple times!

All these features enable it to be shockproof and rugged.

Multiple Reticles:

Never confine your options when every shot matters! Next up in this Holosun 510C review, we’ve got you the ultimate feature that has become the reason for this RDS fame. Equipped with three different reticle options, this red dot sight is one of the market’s leading ones.

It has 2 Minute of Angle (MOA) dot, a 65 MOA Ring, and a 2 MOA dot with a 65 MOA ring. Professionals vouch for this MOA dot sight and its switching between the settings, as it helps the shooters for easy target acquisition in every scenario.

This way, you can also use the field of vision with both eyes open.

You’ll get a red and a green reticle with it. Opt what works the best for your eyes! Furthermore, this red dot sight is perfect where short-range is concerned as compared to a micro red dot.

Water-Proof Ability:

Rough and tough shooting never completes without getting into the mud or water! Worry no more, as this Holosun 510C can go down up to the depth of 1 meter. Also, with an IP67 rating, you’re not going to miss your shot due to wet and humid weather.

Dual Power Supply:

Don’t you get impressed if we tell you that you can utilize the dual power mode for a continuous run? It features a solar panel to switch between the battery and solar as per the ambiance.

Therefore, do not worry about the shots in the day and night time with 12 levels of brightness, i.e., 10 for day and 2 for night time.

The CR2032 battery can last for 50,000 hours for a much better shooting experience.

Parallax Free:

Never put a strain on your eyes! That’s not the part of Holosun HS510C problems as well.

You get a parallax-free vision with no obstruction via utilizing this reflex styled red dot sight. Get unlimited eye relief with push button (+) (-) controls and a motion sensor for Shake Awake!

(The red dot sight powers down after no use for 10 minutes).

Surprisingly, you’ll get no blue in targeting due to the LED emitter and works best with Aimpoint 3X for most shooters.

QD Mount:

Next up in this Holosun HS 510c review, we have an exciting feature to discuss, i.e., the Holosun HS 510C mount! It has a quick-release mount system that fits nicely on the Picatinny Rail system (as tested on the Glock Roni Conversion Gun). This way, you can attach or detach the red dot sight in a breeze.

Holosun 510c With Magnifier:

If you’re shooting something within 200 yards at various unique positions, a magnifier is what you’ll need to enhance your red dot. Personally, I own the Holosun HM3X Magnifier and it works great in the absolute co-witness configuration. Indeed bang for your hard earned Benjamins. You can look for a deal here on Amazon.

It works well and the combo looks cool as *uck!
