Description

The Holosun 407C/507C X2 series is an open reflex sight engineered for full- sized and compact pistol applications, offering advanced features in a durable, lightweight design. Whether for duty use, competition, or everyday carry, the 407/507C X2 delivers the reliability and precision demanded by serious shooters. At the core of the 407C (Dot-Only) / 507C X2 (Multi-Reticle) is Holosun’s innovative Multi-Reticle System (MRS), allowing users to seamlessly switch between a precision 2 MOA dot, a 32 MOA circle, or a combination of both to adapt to their shooting needs. Powered by Holosun’s Red Super LED, the sight provides up to 50,000 hours of battery life on setting 6 and includes Shake Awake technology, which automatically powers the optic on with motion and off when idle to conserve battery life. The addition of Lock Mode, originally developed for Holosun’s law enforcement models, prevents accidental setting changes by locking the side control buttons—an ideal feature for defensive and professional use. The Solar Failsafe backup ensures your optic stays operational in the event of battery failure by automatically switching to solar power in daylight conditions. Constructed from high- strength 7075-T6 aluminum with a hard anodized finish, the 407/507C X2 is built to withstand harsh conditions. It features an industry-standard RMR footprint and a side-mounted battery tray for easy battery replacement without unmounting the optic.

Frequently asked questions

The Shake Awake feature of the Holosun Reflex Sight is designed for power conservation. If the unit has not moved for a certain period, this feature will put the sight into sleep mode. Once it senses motion, it immediately powers back up and is ready for use.

The 2 MOA (minutes of angle) dot in Holosun Reflex Sight is the spot size at 100 yards, meaning it covers 2 inches at that distance. On the other hand, the 32 MOA circle provides a larger field of view which can be beneficial during rapid target acquisition situations.

The difference between the red and green dot in the Holosun Reflex Sight is primarily a matter of personal preference. Some individuals find the green dot to be more visible in daylight. However, performance wise, both colours provide the same functionality.

Parallax-Free means that the dot in the Holosun Reflex Sight stays in alignment with the firearm, irrespective of the shooter's eye position. This provides a significant advantage in rapid target acquisition and shooting accuracy, especially in high-stress situations.

  • Some of the best dollar to performance optics out there
Color: Black Reticle type: Multi-Reticle - Red
I have never had a problem with performance, clarity or durability from any of their products. Mounted on everything from 12ga to 22lr, pistol, rifles..zero problems. Its a perfect optic for east coast deer hunting with sub 200m distances on a lever gun or 300blk/450/x39 SBR. The 2moa dot allows fine aiming without the dot covering 90% of your target at 100m and the circle allows "eyeballometer" windage and elevation adjustments. ... show more

  • NICE
Color: Black Reticle type: Multi-Reticle - Green
Always wanted a reflex sight. Did some research and found this one was one of the top functioning sight priced them everywhere all of them were $40-$50 more. Install was super easy on a shadow systems MR920. Zero with a bore scope, also super easy. Now it is spot on. Don’t use the circle much but for quick target acquisition would be good, well thought out, shake awake is neatsaves battery life but with 50k hours battery life if I change it every year I will never run out of battery. Plus has solar “back up” ... show more

  • Great EDC Red Dot
Color: Black Reticle type: 2 MOA Dot - Red
It's a Holosun, I expected it to be very well made, and my expectations were met, its a great red dot, the 2 MOA dot isn't as difficult to find as other would suggest just takes some practice with it, looks great on my EDC though and for the price it is definitely worth it.

  • Must have for any handgun
Color: Black Reticle type: 2 MOA Dot - Red
I recently mounted the HOLOSUN 407C/507C-X2 on my Glock 19, and it works perfectly. The fitment is secure, and it holds zero flawlessly even after several hundred rounds at the range. The build quality is rugged, and the side-loading battery tray is a huge plus since you don't have to remove the optic to swap batteries. The reticle is crisp, and the solar failsafe provides great peace of mind. If you’re looking for a reliable, duty-ready red dot for your Glock, this is easily one of the best bangs for your buck. Mounting Tip: To ensure it stays rock-solid on your G19, I highly recommend using a tiny drop of blue Loctite on the mounting screws and using a torque wrench to hit the manufacturer's spec (usually around 15 inch-pounds). ... show more

  • Crisp reticle, shake awake, solar charger. Too dim in sunlight
Color: Black Reticle type: Multi-Reticle - Red
Great pistol optic. Very clear in lowlight and darkness. Very crisp reticle and took very little adjustment. BUT…reticle washes out in bright sunlight. Love the auto brightness feature, and the battery backup solar charger. But it does not have a setting quite bright enough. Looking into other options. ... show more

  • Solid Choice
Color: Black Reticle type: 2 MOA Dot - Green
I chose Holosun because I've used their products for years. I prefer the green dots to the red ones, and Holosun offers many green dot choices. To me, Holosun is a mid-tier sight makers, not the top end of the price point, but not bargain-basement, either. For a potentially life-saving tool, it's something I'm willing to pay a bit more for, but given my good history with Holosun, I am satisfied that these will work if I ever really need them to work. I probably own five or six Holosun sights, which speaks volumes. ... show more
