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


This is a one piece Springer Precision aluminum optic plate for mounting a Trijicon RMR, Holosun 507c Holosun 509T, Vortex Venom/Viper and Burris Fastfire. (The Burris Fastfire will not work with the auto brightness feature). This mount uses the two forward screw holes in your slide cut to attach our mount to the slide with our provided hardware. The rear holes on the mount are for attaching the optic. These come with our provided screws and thread locker. Also comes with a black rear sight and fiber optic front. This mount is designed to move the optic back to the rear of the slide behind the rear dovetail, away from the ejection port of the firearm - keeping the optic lens cleaner. 

1.0 oz with optic hardware.

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 commemoritive 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.
