The B.Mag isn't simply a re-chambered version of an existing platform; Savage designed this rimfire rifle specifically to handle the high velocities of the 17 Winchester Super Magnum with design features typically reserved for their centerfire rifles. In order to maximize accuracy in this long-range shooter, the B.Mag utilizes Savage's thread-in-barrel headspacing system, rear-locking lugs, and a cock-on-close bolt capped off with the light, crisp AccuTrigger. It has a flush-fit center-feed rotary magazine. The B.Mag also has a soft rubber buttpad and hidden action-screws in a lightweight, black synthetic one-piece stock.
