Holosun HS507C-X2 Pistol Red Dot Sight - ACSS® Vulcan® Reticle

I was very impressed by the quality and ease to use. I used it on my new MP 9mm compact. I did have to buy a base plate from C&H PRECISION which fit like a glove. You get your moneys worth without breaking the bank.

Bought one of these when they were first released. Thought it might be a gimmick but was sold as soon as I tried it. The reticle is a game changer for awkward shooting positions. I have been using the Trijicon RMR on pistols for more than a decade and I am switching. The RMR is a fantastic red dot and very durable but the ACSS reticle is just so good. I wish Trijicon would license the reticle from Primary Arms for the RMR. Primary Arms is also a great company.

Awesome sight for the money. Crystal clear optics that greatly improve time on target shooting.

This is the only sight that works with my astigmatism. I have wasted a couple grand on red dots trying to find one that projects a crisp dot. If only I had waited for this one. It took so long to get in stock so I tried many other brands and reticle with zero success just a blowout dot but finally I got my hands on it and it is a dream come true. Now I just need to find out if the holosun hs503g acss has the same emitter.

First, the sight came with a lot of different mounting screws, each pair in a separate bag with the screw specifications stamped on the bag. Second, using the sight is a joy! With a normal red dot I very often find target acquisition difficult when moving, taking cover, and shooting single-handedly. The outer ring is VERY effective in bringing the reticle back to center in these situations.

Extremely easy-to-use optic at a great price point for those looking for a competitively priced, clean and clear micro. The controls are easy to access, the aiming point is sharp, and the solar power back-up and the 250 MOA reference circle are game changers. Adding this optic to a rifle system would be a breeze, as well, as the 250 MOA circle can be turned off at the operator's will.

This will be the go-to for my future MOS Freedom Seed Dispensers.

This is the best pistol optic on the market. I hope some USA made manufacturers will incorporate this design soon. The reticle is like nothing else, target acquisition is so intuitive that after some training, you can hit center of mass targets without actually even seeing the target chevron in the optic. Because you know what the full reticle looks like, and where the central chevron is in relation to the shape of the outer circle, you can fire on target even if all you see through the reticle is part of the outer circle. Another way to say what I'm trying to describe is that you can hit a target without aiming at it, without aligning your eye with the center chevron over the target. Groundbreaking reticle, good job PA.

i put one of these on my M&p 2.0 core pistol, with the apex flatty trigger. this is a excellent optic quick target acquisition and in the auto adjust mode have been able to pick up dot in all lighting circumstances. Holosun/primary arms knocked it out the park on this one!

Love it. Game changer technology. I held out on red dot pistol sights until I saw this. And Primary Arms is always good to go.

Excellent red dot and the ACSS reticle is fine. The large circle helps find/center the reticle quickly without having to hunt for it if you don't get a perfect sight picture.
