Vortex Viper/Venom (fits Burris FastFire and Docter) Optic Plate Red Dot Mount for Sig Sauer P365/P322

EGW Red Dot Sight Mount Adapter Plates are designed to fit Docter footprint micro red dots onto Sig Sauer P365 Optics Ready pistols. They are meant to be installed in place of the factory mounting plate or optic that uses the smaller RMSc footprint. With an EGW Sight Mount, you can mount an AT3 ARO, Vortex Viper, Vortex Venom, Burris FastFire,  or Docter red-dot sight on your Sig Sauer P365 pistol.

This mount is easy to install and remove. Simply remove the sight plate on your gun and replace it with the EGW Sight Mount. With the EGW Sight Mount, you can take off your red dot sight and replace your rear sight at any time.

The compact size of this mount allows it to fit seamlessly onto your firearm, without adding any unnecessary bulk or weight. This is particularly important for firearms that need to remain lightweight and concealable, for use in both competitive shooting and everyday carry.

Mounting hardware is included with this mount. The screws that are included with this mount require a 5/64” Allen wrench for installation. Two button head cap screws are provided for Vortex Viper and Venom sights, and two flat head cap screws are provided for Burris FastFire and Docter sights.

Easy to install and use, the EGW Docter Optic Plate Red Dot Mount is compatible with most Sig Sauer P365 pistols and a wide variety of micro red dots. Expand your handgun’s accuracy and capability with this adapter.
