I recently Acquired an older Model 10 Tactical with a flat back action. Is my action screw spacing going to be compatible with the current short action chassis systems. The screw spacing is 4.275. I can't find specs on action screw spacing in the MDT website. I think that I want to Fit this into the Oryx Chassis but want to make sure it will fit. Also This action is a staggered feed I believe..... Any help would be great! I'm new to Savage rifles.
