Winchester SX4 Universal Hunter 20 Gauge 28" Semi-Auto Shotgun

The Winchester SX4 Universal Hunter delivers rapid follow-up shots and versatile hunting performance in a lightweight 20-gauge platform. This semi-automatic shotgun combines Winchester's proven Active Valve gas system with Mossy Oak DNA camouflage for effective concealment across diverse hunting environments.

What Makes This Different

The Active Valve gas system automatically adjusts to different loads without manual intervention, cycling everything from light target loads to heavy 3-inch magnum shells reliably. Unlike traditional gas systems that require adjustment or cleaning between load changes, the SX4's self-regulating design maintains consistent function across the full spectrum of 20-gauge ammunition. The chrome-plated chamber and bore resist corrosion while maintaining accuracy over thousands of rounds.

Key Features

• Active Valve gas system cycles 2¾" and 3" shells automatically without adjustment
• 28-inch barrel optimizes velocity and swing characteristics for upland and waterfowl hunting
• Mossy Oak DNA camouflage pattern provides effective concealment in varied terrain
• Includes three Invector-Plus choke tubes (Full, Modified, Improved Cylinder)
• 4+1 capacity with drop-out trigger group for easy maintenance
• Aluminum alloy receiver reduces weight while maintaining strength
• Back-bored barrel technology improves shot patterns and reduces felt recoil

Field testing demonstrates consistent cycling across load weights from 7/8-ounce target rounds to 1¼-ounce waterfowl loads. The 28-inch barrel length provides optimal ballistic performance for hunting applications while maintaining manageable swing weight. Weather-sealed action components function reliably in wet conditions, and the hard chrome bore finish resists fouling buildup during extended shooting sessions.
