509 SERIES

This collection contains the Holosun 509T X2, an enclosed red dot for pistols. The closed housing keeps rain, mud and dust away from the LED. It uses its own Holosun 509T footprint.

• Reticle: red or green.
• Mounting: on a plate or mount with the Holosun 509T footprint, or on an RMR plate with a footprint adapter. See Footprint adapters.

To mount the red dot on a pistol with an optic cut, you need a plate with the same footprint. See Optics ready plates. For all Holosun red dots, see Holosun.

Frequently asked questions

Does the 509T fit an RMR plate?

Not directly. Use a plate with the 509T footprint or an adapter from RMR to 509T.

Why an enclosed red dot?

Rain, mud or dust cannot block the LED, so it works in bad weather.
