G'Day Fella's

Check out> www.xssights.com They manufacture Ghost Ring sights that will attach to a swag of different Rifles.
They also have models that attach to some brands of scope mount bases, so you can attach them as a Back-Up sight, in case of scope failure, etc.
But don't forget, you'll need to have a front sight for this to work properly!!!

I hope this may be of some assistance?
