What's your budget?
If it was me I would be going on a shopping spree at Unknown Munitions and I would buy the following.
BAT Vesper Medium, RH, Magnum bolt
UM DBM Medium
UM Mag Medium XL Magnum
UM Premier rings
SRS Pro 3 self timing brake
Shoot2Hunt RokStok R700 medium, trinity rail 3B contour
All of that is in stock and ready to ship. For $3,305 + shipping
For the barrel I'd get an Osprey Barrel Works prefit from Patriot Valley Arms in the .750 taperless contour
Precision rifle prefit barrels for all actions, custom ordered and ready to install. No machining or gunsmithing required. Match winning Osprey barrels by Patriot Valley Arms; we Engineer Repeatability. 100% Made in USA

For the trigger I would find a Geissele Super 700
Ship everything to Patriot Valley Arms for assembly. Have Unknown Munitions load ammo for it. Call it a day
