Home Forums Hunting & Shooting Custom Rifles & Wildcats McMillian Inletting for a Tikka T3

I am looking at buying a used GS that is inletted for a T3. The fella also has it inletted for the Atlasworx BM in a LA....he was using it on a 6.5x55 Swede. So my question is, is the inletting the same for the BM from McM regardless of the caliber? Can I simply swap the bottom metal to a SA and run a .243 out of this?

Tikka T3's all have the same bottom metal (Plastic) only the plastic magazine and bolt stop change it from SA to LA.

Unfamiliar with the Atlasworx BM but if it fits in the inlet for a Tikka LA it will fit the SA
