All X-Bolts come with a detachable rotary magazine. The magazines are made from a tough—really nearly indestructible—and lightweight polymer. The magazine’s design positions the top-most cartridge dead center within the action and in line with the bolt so all rounds feed straight into the chamber.
The magazine sits flush in the stock and is released by a catch that is a part of the magazine, so that the magazine slips very naturally into your hand when you release it, a well-thought-out ergonomic detail. My favorite innovation with this magazine, however, is the molded contours in the magazine’s interior. These contours snug up against the shoulders of the cartridges so that under recoil the tips of your bullets will not slam against the front edge of the magazine.
New Scope Mounting System
Browning’s engineers have modified the mounting system on the X-Bolt so that each scope mount is secured to the receiver by four screws instead of the more traditional two, the idea being that with four contact points the bases will tend to align with more precision. (Of course, why not just skip the issue all together and design a receiver with integral bases? This is a concept familiar to owners of Rugers and is appearing on a growing number of firearms, especially AR-style rifles, as well as the Thompson/Center Arms Icon, introduced last year.)
The barrels on the X-Bolt are free-floating and the actions are bedded at both the front and the rear for improved accuracy potential. The barrels also come with recessed crowns to protect the rifling at the muzzle.
The X-Bolt has a two-position tang-mounted safety. With the rifle on safe, the bolt is locked in place though Browning has added a button at the top of the bolt handle, which lets the user open the action with the safety on.
