Details
Description
Holosun HE509T-X2 Green Dot Sight seals a green emitter inside a Grade 5 titanium housing — fully enclosed, unlike the open 508T, so lint, dust and rain never reach the emitter. Adjustment is 1 MOA per click across ±30 MOA of travel, and the Multi-Reticle System offers a 2 MOA green dot, a 32 MOA circle or both as a circle-dot.
How It Compares
In red or gold, the HE509T-X2 Red or the Gold. Prefer the open-emitter titanium optic? The HE508T-X2 Green. More enclosed red dot sights are collected here.
