Mossberg SA-20 All Purpose Field 20 Gauge Semi-Auto Shotgun 26"

The Mossberg SA-20 All Purpose Field delivers reliable semi-automatic performance for upland hunting and clay sports. This 20-gauge platform combines manageable recoil with effective stopping power, making it suitable for hunters seeking versatility across different game types.

What Makes This Different

The SA-20 features a gas-operated system that cycles 2¾" and 3" shells reliably without adjustment. Unlike pump-action alternatives, the semi-automatic operation enables faster follow-up shots during fast-moving bird encounters. The 26" barrel length provides optimal balance between swing dynamics and velocity retention for field shooting.

Key Features

• Gas-operated semi-automatic action cycles 2¾" and 3" 20-gauge shells
• 26" ventilated rib barrel with blued finish reduces mirage and heat buildup
• 4+1 capacity provides adequate firepower for upland and waterfowl hunting
• Turkish walnut stock offers traditional aesthetics with functional ergonomics
• Blued steel receiver provides corrosion resistance in field conditions
• Right-hand configuration with standard trigger guard accommodates most shooters
• Accepts standard choke tubes for shot pattern customization

Field testing demonstrates consistent cycling across various ammunition weights and manufacturers. The 20-gauge chambering reduces felt recoil compared to 12-gauge alternatives while maintaining effective range for dove, quail, and pheasant hunting. Weather-resistant finishes protect critical components during extended outdoor exposure.
