Description

The Holosun 507C-X3 updates the classic 507C with a refined, modern housing and engraved Holosun logo while keeping the proven performance shooters rely on. Built to the popular RMR footprint, the 507C-X3 mounts cleanly to a wide range of full-size pistols and adapter plates, making it an easy upgrade for everyday carry, duty, or range use.

At the core of the optic is Holosun’s Multi-Reticle System (MRS), allowing you to choose between a precise 2 MOA dot, a fast 32 MOA circle, or a combined circle-dot reticle. Available in Red, Green, or Gold, the reticle options let shooters tailor visibility to personal preference and changing lighting conditions.

The 507C-X3 features Solar Failsafe and a forward-facing photodiode that automatically adjusts brightness as ambient light changes, while manual brightness control with lockout and memory modes ensures consistent settings when you want full control. With up to 100,000 hours of battery life from a CR1632 battery, this optic is built for long-term reliability.

A low-profile, compact design keeps the optic holster-friendly, while the rugged 7075-T6 aluminum housing, IP67 waterproof rating, and 5000G vibration resistance ensure the 507C-X3 can handle hard use. The result is a familiar optic with updated ergonomics, clean styling, and dependable performance.

This red dot sight features a crisp reticle with clear glass and improved X3 housing design. Customers praised the "very clear glass" and noted it "held zero" during use. The auto-brightness performs well though some found it slightly off in extreme lighting. Shoppers appreciated the MRS reticle options and solar failsafe. Compatible with RMR footprints for pistols and rifles.

Much improved over the X2, which was already a proven optic.

Much nicer compared to the X2. I like the new aggressive angles and embossed logo rather then bright white etchings. Glass and reticle is more crisp than my RMR Type II. The X3's auto-adjust also beats the RMR Type II; however, the SCS MOS light sensor beats both. No hiccups shooting on my 9mm pistol. It held zero and looks great while at work.

I have a lot of time and rounds behind the rmr hd

I have a lot of time and rounds behind the rmr hd. I really think this optic is better. In every way other than not being made in the US.

Looks GREAT... just wish the green was out

Felt putting the latest generation of 507C with the flat top on the latest generation of Glock 17 was only right. Along with one of the newly machined C&H filler plate, only made sense. It looks GREAT!!

This was exactly what I wanted to get. The shipping and tracking were excellent and it arrived on schedule. Can't wait to put this NEW Holosun sight on my Kimber 9mm and show it off to friends and family. -Freedom Gorilla will continue to get my business and will be a go to for future purchasing gun accessories and other items here on out. Great job and nice piece!

Fast shipping and excellent site

Shipped quick, communication was outstanding and personable, product was exactly as described.

Thanks again FG!

Crisp reticle

Very clear glass. Crisp reticle. Love the new housing on the X3. Too soon to discuss reliability but perfect so far. Only a minor quibble - the auto brightness is good but not great. A little too bright in darker light. A little too dim in bright light.

I decided to mount this optic on one of my lever

I decided to mount this optic on one of my S&W 1854 lever rifles in .357 mag. Great setup.

Great optic

Freedom gorilla was the first time I saw the 507c x3. I was going there to find the x2 ,but the x3 was available and I'm sure glad that I went with it. The eye on the front makes the auto brightness mode work much better. The optic arrived quickly and the dpp plate for the most let's the optic sit low enough to get a lower 1/5 co witness with the factory sights. And in a side note I have a astigmatism and the 2moa sit and the 32mia circle are perfect with my corrective lenses.
