Below are the Holosun 507 Comp Red & Green dot sights. These are offered at the best price with free shipping.
The Holosun 507 Comp is a competition pistol red dot sight with a large window. These optics have a Trijicon RMR footprint, so they will mount to any RMR footprint slide, or adapter plate.
Their window is very large compared to traditional pistol red dots. The reticles also come with the CRS System (Competition Reticle System). This gives you a 2 MOA Dot, and then a combination of an 8, 20, or 32 MOA outer ring.

Even with my astigmatism I can see the chevron clear as can be with only slight halo’ing (but thats with everything I look at) installed it as soon as got it on my MR920P. Cant wait to get it to the range
Still waiting on my stuff from jeggerwerks
Order and delivery time were great. When parts were received, they looked identical. No way to tell which bag of screws went with which gun.
Perfect fit, good quality and all the materials to properly install.
Great red dot and the service is premium.
I was at the range (April 2025) when the battery tray, battery, and battery tray screw popped out of my EPS Carry Red Dot. I found anll of the red dot components except the battery tray screw. I called and emailed Holosun for a replacement, however they had slow and disinterested customer service representatives (took me multiple follow up emails to get them to do their job). I immediately purchased the replacement screws from Freedom Gorilla and they arrived quickly and worked perfectly. They just needed some thread lock. Holosun’s backup screw arrived 12 days AFTER Freedom Gorilla’s screws. I definitely recommend people give Freedom Gorilla a try as I was skeptical at first (small unknown website) but ended up being impressed by their product.
The optic is great,very clear, and these guys help out any time you need it
Thank you for helping me get all the correct parts
I migrate from a 507C to a 507K with the RXM. Without any screws, the "C" series optic swivels a bit from side to side but the "K" series optic sits firmly in place (with just the adapter plate). I also like how the "K" series optic is more compact. Even with the adapter plate, the "K" series optic appears to co-witness better than the "C" series optic with no adapter plate.
Very fast shipping and detailed instructions! Will purchase again !
