Browning's Buckmark URX air pistol uses a single-stroke cocking mechanism with break-barrel action for easy operation, making it great for plinking and small-varmint shooting. The URX's spring piston sends .177-caliber pellets downrange at 320 fps from the fully rifled barrel. Ergonomic ambidextrous grip is super-comfortable and builds confidence in your shot and aiming control. Adjustable rear sight and fixed front blade. Integrated Weaver rail for mounting optics. Automatic safety. Caliber: .177. Barrel length: 5.25". Overall length: 12". Weight: 1.5 lbs.
