Anybody know an easy (no drilling) way to mount a red dot scope (preferably a Trijicon) to existing milled in scope base?

Check out Midway. I think someone makes a Weaver type base that locks into the Ruger base cutouts.

B Square makes a weaver base that fits into both ruger type bases. I wonder if one of these could be cut to size for a red dot ?

Burris makes a Ruger mount for their FastFire II; I have it on my RSM in 458Lott and killed a tuskless with it last September. I have no idea if it will fit the Trijicon.

Burris will do I'm sure. Thanks

Just sent you a PM.
