Switching Reticles
Switching between the 65 MOA reticle and the 2 MOA dot is very simple and quick. Simply turn the selector to the reticle symbol. Turning it back to the reticle symbol switches the reticle to the 2 MOA dot.
Designed For The Following Firearms
Holosun red dot sights are compatible with all types of firearms. They can be used on everything from pistols, semi-automatic rifles, and shotguns to large-caliber hunting rifles such as the 9.5×73.
- Hunting rifles and shotguns
- Weapons such as the SA 58, AR-15, and AK-47/74
- Guaranteed recoil resistance up to 9.5×73 (.375 Weatherby)
Night Vision Support
HOLOSUN sights are compatible with night vision devices. For use with these devices, they feature two brightness levels that are otherwise invisible to the naked eye in normal conditions. These are the first and second brightness levels, which are compatible with night vision.
Installation Of The Sight
Holosun red dot sights come with two Picatinny/Weaver-compatible mounts.
Low-profile mount with an 8mm height and a 1/3 co-witness mount. With these mounts, the red dot sight can be mounted on hunting rifles and shotguns, as well as semi-automatic rifles.
Optics cover
HOLOSUN rubber covers are included as standard with the 403 series and 503 series, with the exception of the 503FL model. The flexible cover fits the scope very snugly and protects it during transport and when the firearm is stored in a safe. Removing the cover is very quick.
Parallax-Free
HOLOSUN sights are designed to be parallax-free. Unlike when using open sights, the shooter does not need to look through the optical axis while firing. This feature allows the shooter to react instantly. Simply align the reticle with the target and pull the trigger. This advantage is particularly appreciated by hunters and shooters in tactical disciplines.
Reliability Under Recoil
The sight can withstand an impact of 1,000 G, which is equivalent to a 9.5×73 (.375 Weatherby) caliber.
It’s also perfect for hunting and sporting calibers, including shotguns.
The Dot Sight and Eye Conditions
Please note:
- Using this sight in combination with astigmatism may be problematic.
- If you wear glasses, you should wear them while shooting.
Included In The Package
The package includes a red dot, a high 1/3 co-witness mount and a low (8 mm) mount, a Torx screwdriver, and a microfiber cloth.
