Rock Island CR103 Meriva 12GA Semi-Auto Shotgun 18.5" 5+1 Black

The Rock Island CR103 Meriva delivers reliable semi-automatic performance for tactical applications and home defense scenarios. This 12-gauge platform combines proven gas-operated mechanics with modern synthetic construction for consistent cycling across various ammunition types.

What Makes This Different

The CR103 Meriva features a chrome-lined barrel and chamber system that resists corrosion while maintaining accuracy over thousands of rounds. Unlike basic pump-action alternatives, the gas-operated semi-automatic action provides faster follow-up shots with reduced operator fatigue. The 18.5-inch barrel length meets federal requirements while maximizing maneuverability in confined spaces.

Key Features

• Gas-operated semi-automatic action with 5+1 capacity for rapid target engagement
• 18.5-inch chrome-lined barrel with 3-inch chamber compatibility
• Black Parkerized metal finish provides corrosion resistance and reduced glare
• Synthetic stock and forend resist weather damage and impact
• Standard Picatinny rail system accommodates optics and accessories

Field testing demonstrates consistent cycling with 2¾-inch and 3-inch shells ranging from birdshot to slugs. The gas system adjusts automatically to different loads without manual intervention. Law enforcement agencies report reliable function in adverse weather conditions including rain, dust, and temperature extremes. The synthetic furniture maintains zero shift even after extended use.
