Holosun HE509T-RD-X2 Enclosed Solar Powered Red Dot Sight

The HOLOSUN HE509T-RD-X2 is solid—super clear, easy to use, and built like a tank. Love the enclosed emitter and the reticle options. But what really made the whole experience great was Primary Arms’ customer service. They kept me in the loop the whole way and made sure everything went right with my order. It’s not every day you deal with a company that actually seems to care. Between the optic and how well they treated me, I’ll definitely be coming back.

Second one of these and have had no issues with these on duty weapons. Enclosed emitters are great for the elements and I have always liked that Holosun has offered different reticles. However I really do thing they should offer smaller and larger MOA options on these guys in addition to upgraded reticles like on their 507 comp. Great optic either way and much prefer them over most open emitters.

This was my first Holosun optic, and I’m very impressed with it. Much so that I’ve debated switching out my RMR on my edc for another 509T. Right now mine lives on my P320 Xten, and after close to 1,000 rounds it’s held zero after what I’ve put it through so far. Solid housing, good price point, super bright reticle, and the glass is clear.

I have over 3K rounds on two of these optics and have not looked back since. Great size window with lots of features and is very reliable. Mount it, zero it, and your good to go!

I decided on this after watching Sage Dynamics 10k round update. It survived all his punishment and held zero. I tried it on the circle dot but didn't like it so I run it on the dot only and right out of the box it was dead on at 25 yards.

Was skeptical at first but now essential on my carry pistols. Very clean reticle and even with my mediocre eyesight quick pictures and no fracturing like some other cheaper dots

the holosun that everyone knows and loves but better. clearly well built, sighted in easily, and operates as it should. the red dot everyone should own.

Got this as my very first optic and running it on a SA 5" Prodigy as a duty rig. Liked the ease of use not complicated at all. After getting used to using it, I am sold on pistol optics. It doesn't make a pistol shooter good; but it will make a good pistol shooter better/faster.

I had my slide milled by JagerWerks to direct mount the 509T and it sits very low. I use standard height sights as back up. I like the option of three different reticles. It also very convenient that the battery is replaced without having to remove the optic. I prefer the way the mount clamps on as opposed to other designs that have screws going down into the slide. So far I’ve shot a few thousand rounds through it. The only issue was it began to loosen up so I torqued to 25 inch pounds and added blue loctite. It’s been good since. Highly recommended. I actually bought a second one and I’m waiting to get that slide milled.

We know Holosuns are top notch, and offer a solar cell backup. But only PA will let you have one for as low as $299!
