Tritium Front Co-Witness Optics Mount for Sig Sauer M17/M18/X5 Legion


This optic mount is a one-piece aluminum plate designed for mounting a Trijicon RMR, Holosun 507c, Holosun 509T, Vortex Venom/Viper, and Burris Fastfire. The Dawson Precision tritium sight set it comes with will help you see your iron sights in low light conditions. This mount is designed to move your optic back to the rear of the slide, behind your rear iron sight. This moves your optic further away from the ejection port, keeping your lens cleaner.

It uses the two forward screw holes to mount to the slide, and the rear screw holes to mount your selected optic to the plate. Springer Precision provides hardware and thread locker along with the optic mount. 1 oz with optic hardware. Updated pictures coming soon.

Installation Instructions

** Springer Precision can only guarantee the the mount will fit models and optics listed.**

**Designed to only fit the Sig Sauer P320 M17, P320 M18, P320 X-Compact, X-Full, X-Carry Legion, and X-Five Legion slides. WILL NOT FIT OTHER MODELS and may not work on Military issue M17 models or commemorative editions.**

Does NOT work with the RX, Original X-Five/X-Carry (for Romeo1) or Pro/LE Pro P320 models. 

Does NOT work with Trijicon SRO.

Holosun 509T does not require extra optic screws as it attaches to our mount with the micro rail and does not use the RMR adapter plate supplied by Holosun.

The ACSS Vulcan 509T will hang off the end of the optic mount/slide, so we do not recommend using our 509T mount for it.
