Holosun 507C X2 Red Dot

The Holosun 507C X2 Red Dot Sight provides a large field of view paired with useful features that will help you stay on target while greatly reducing target acquisition time. The new X2 version offers upgrades such as a side access battery tray, which allows the operator to change the battery without un-mounting the product. Holosun machined this product from light yet rugged 7075 T6 aluminum and added a multicoated lens that provides a bright, crisp sight picture.

 The Holosun HS507C X2 LED Red Dot Sight uses both Solar Failsafe technology and a high capacity lithium battery to power the optic, ensuring you’ll always have a reliable point of aim in the field. These optics are designed with Shake Awake technology that senses motion to power the sight on and off, and last setting recall ensures you don’t lose your customized options once the unit powers down. This model offers up to 50,000 hours of battery life. All versions are projected from the same LED, so no re-zeroing is needed when changing reticles. Enhance your shooting skills and create a better experience at the range by equipping your firearm with a Holosun HS507C X2 Red Dot Sight.

Holosun 507C X2 FAQ’s

Q. How to switch to solar power only

A. In automatic mode the solar optics will use the solar panel but automatically switch to battery power whenever there is not enough light available to power the reticle.

A. Most, the Holosun 507c has an identical footprint to the Trijicon RMR and is compatible with any of its mounting.

Q. Holosun 407c vs Holosun 507c

A. The Holoson 4 series only offers a 2MOA dot as for the 5 series features the multi reticle system (MRS).

5 reviews for Holosun 507C X2 Red Dot

  1. Clif Rawlings (verified owner)

    Excellent optic. I have the standard 507c x2 in red and now 3 of them with the ACSS reticle (2 red and 1 green reticle). I think the large Vulcan outer circle is the biggest advantage of this optic. Much faster Target acquisition and less hunting for your dot/ reticle. I have a slight astigmatism and the green chevron reticle is a little blurry/blooming to me. Where as, the red reticles are very clear. This will be different for each person so I recommend looking through both colors before purchasing. I have been very impressed with Kenzies excellent service, fast shipping and great prices.

  2. Dennis Brindle (verified owner)

    Installed really quickly and sighted in and it works very well it has been a god send as I can see it very well and has put fun back in shooting for me. And the service from Kenzies is excellent..Also the dot on this site is very sharp..I have had some red dots that leave a lot to be desired when it comes to clarity.

    Great RDS. Side mounted battery and multi reticle system is great. For someone who has astigmatism issues with red dots, the 32 moa and 2 moa combo gets rid of that fuzzy sight. Zero issues mounting this to my Glock Triarc slide w/ RMR cut. . If you want something more durable, get the 508 with the titanium body. Otherwise, this sight is more than enough.

    There is a ever so slight magnification due to the curvature of the lenses. Maybe 1.1x or 1.2x. Not a big deal and it won’t bother you after you get used to it. You only notice it is someone points it out. Also has a slight blue tint but nothing bad. 5/5 optic for the money. 508T is next! Thanks for the fast and quick shipping!

  4. PETER THOMSON (verified owner)

    Having owned the Trijicon RMR on an M&P compact I decided to try the Holoson 507C on a Glock 19 5 MOS.
    Trijicon Version 2 is a truly excellent piece of equipment however, Holoson should be taken as a serious contender from both the features and value standpoint. They are proving to be innovative in their continually improving product offerings and testimony to this is the difficulty in obtaining any of the “new T” series Holosons. Kenzies gave great service and I highly recommend both Kenzies and Holoson,

  5. Geoffrey Blanchard (verified owner)

    Excellent RDS and the V2 is great with the new Battery mount on the side. Never have to take the optic off the slide to change the battery. The sight is bright and the auto feature works great for me. The brightness buttons are big and very tactile. I mounted this RDS on my new Sig P320 M18.
