Rifle Scopes Sako TRG mount - Tikka Varmint .338 WM

Not sure about the mount you're speaking of directly but the Sphur mount for the TRG fits the Tikka T3 rails. The only thing though is you have to lower (enlarge) the ejection port.

The dovetail of the Sako TRG mount will fit, but likely not the recoillug. So new recoillug holes had to be made in the action. And you have to enlarge the ejectionport.

All those modifications are perfectly safe and very quickly done in a millingmachine.
