Scope Mount - Browning Gold 10

[bowmaster5687]

Looking to have my gold 10 drilled and tapped for a mount. In particular this one http://www.brownells.com/optics-mounting/rings-mounts-amp-bases/shotgun-bases/shotgun-scope-mount-prod7632.aspx. Problem is I need #4 and it is not available for sale. I'm looking to mount a Burris fast fire 3. Any recommendations besides a saddle mount?

Check out a base for a 10-22 I have used them for years on a number of different shotguns.
