Holosun HE507C-GR X2 Green Dot Reflex Sight is an open pistol-mounted optic designed to provide fast, intuitive aiming on full-size handguns. This green dot version delivers a selectable aiming solution using Holosun’s Multi-Reticle System, allowing shooters to switch between a precise center dot and a larger circle-dot configuration depending on speed or precision needs.
Built by Holosun, the HE507C-GR X2 is intended for pistol users who want a compact, non-magnified optic with extended runtime and minimal maintenance. The green Super LED reticle is optimized for visibility in bright conditions, while Solar Failsafe and battery power work together to keep the optic operational during extended use. Features like Shake Awake and Lock Mode help preserve user settings and reduce unintended adjustments.

Sam (verified owner) –
Great optic at an even better price!
Kenny –
Darn right, Sam! For the price, the 507C-GR X2 punches way above its weight. That 2 MOA dot with the 32 MOA circle makes target acquisition fast as a rattlesnake strike, and with Shake Awake and Solar Failsafe, it’s ready when you need it—no fuss. Can’t ask for much more in a rugged little optic that rides solid with that RMR footprint.

Great optic at a great price
This optic is really the standard, you don't get a better set of features at this price with any other optic and the price after quote is the cheapest you will find a new one guaranteed.

You're right on the money, Zachary. The HE507C-GR X2 is the workhorse of modern optics—rugged, reliable, and packed with features that punch way above its weight. That 2 MOA dot paired with the 32 MOA circle gives you fast target acquisition with precision when it counts, and between Shake Awake and that Solar Failsafe, you're never caught off guard. At this price point, with an RMR footprint and 50k hour battery life, it's hard to justify anything else. Solid call, partner.
