The SX4 takes function, handling and egonomics to the next level. It is built on the self-adjusting, bulletproof Active Valve system that was the core foundation of the SX3. It is also built on that solid operating mechanism with improved balance, controls, and internal operating components. The dedicated hunting machine features critical functional controls that are larger and easier to operate, which is a real benefit in damp weather and cold conditions. Its back-bored technology provides optimum shot patterns that are dense and even, while the Invector-Plus choke tube system offers consistent patterns. The grip area has been totally redesigned for improved comfort and pointability and feels thinner. Both the grip and forearm feature gripping panels positioned to help prevent slipping. The barrel featuers a vent rib, Truglo long bead fiber-optic front sight, and a hard chrome-plated chamber and bore. The SX4 also utilizes quadra-vent ports, drop-out trigger, ambidextrous crossbolt safety, larger bolt handle and bolt release button, and Inflex technology recoil pad. This Compact model features a 26" barrel and a black synthetic stock.
