looking to pick up a .243 barrel for an origin action. Need it to be either for the origin or a savage small shank. 20-22". 1:8" twist preferably but would consider a 1:9. Carbon fiber is a big plus and sendero light profile. In a steel barrel notnlooling for anything over a remington varmit or so. Threaded muzzle 5/8X24 is also preferred. Lmk what you have. Funds ready to purchase.
