Its based on a Rem700 short action but uses Savage type barrels. The bolt body uses a Pierce Eng. Rem700 firing pin assembly IIRC. Rem700 triggers fit such as XMark, Timney, Jewel and TriggerTech.

The action when finished will drop into any Rem700 SA stock. The barrel channel will need opening up for the barrel nut and contour if its not large enough.
