Hi guys,

I've recently bought a Vortex red dot and slide mount for my GSG. Before fitting them I wanted to check if there was anything I needed to be aware of before doing so?

The reason I ask is that I've heard it's sometime necessary to shim the mount to get enough elevation. If this is the case, does the shim go at the front of the mount or the rear?? I'm also assuming it would go between the mount and the red not rather than the mount and the slide??

Any advice is welcome.

Cheers,

B

I shimmed front of mount between sight and base. Only needed a sliver.

Thanks for that. :)

However, having shot it tonight and with the elevation all the way up I was hitting around 2.5 inches lower than the point of aim. Am I right in thinking I need to shim the rear rather than the front?

Which slide mount have you got? I've used both types and never had to shim either of them with any of the red dots I've used (Vortex Razor, Viper, Venom, Shield SMS, RMS, Delta Optical, Vector Optics).

It's the GSG 1911 - Red Dot Pistol Mount - Vortex Venom / Viper / Other from Black Rifle.
