The bolt-action rifle was forever changed with the introduction of the Browning X-Bolt. The X-Bolt builds on the proven successes of past Browning rifles, and adds numerous improvements that place the X-Bolt at the top of any side by side comparison. Most notable is an adjustable three-lever Feather Trigger™ system that offers the best feel on any Browning rifle ever.A bolt unlock button works with the top-tang safety to offer enhanced safety while unloading. Styling features offer more compact dimensions for a smaller, quicker, sleeker look and feel, and also trims weight. To ensure the stability of optics, scope bases are attached to the receiver using four screws per base. Innovation is the Browning tradition, and the X-Bolt is just the latest example.
