The Holosun 509T footprint is used by the Holosun 509T, an enclosed red dot with a titanium housing. Here you find the 509T X2 in red or green. The enclosed design keeps dirt and rain away from the LED.
Mounting on a CZ
On the Shadow 2 OR, choose the CZ or Impact Machine plate for the Holosun 509T footprint. On the P-10 OR, choose the Holosun plate. See Optics Ready plates. If you have a plate or mount for the Trijicon RMR, a Holosun adapter from Trijicon RMR to Holosun 509T lets you use the 509T on it. For a rifle, Contessa makes a QD Picatinny mount for this footprint.
