Shark Coast 300-062-1000-23 5.56 16" Copper Barrel Assembly

The Shark Coast 300-062-1000-23 delivers precision-engineered performance for 5.56/.223 applications with its 16-inch copper-finished barrel configuration. This barrel assembly combines traditional craftsmanship with modern manufacturing tolerances to meet the demands of competitive shooters and tactical professionals.

What Makes This Different

The copper finish provides superior corrosion resistance compared to standard parkerized or blued surfaces, extending barrel life in harsh environmental conditions. The 16-inch length optimizes velocity retention while maintaining maneuverability, delivering approximately 2,950 fps with 55-grain ammunition. This configuration strikes the ideal balance between ballistic performance and practical handling characteristics that shorter or longer alternatives cannot match.

Key Features

• 16-inch 5.56 NATO chamber with .223 Remington compatibility
• Copper protective finish resists moisture and chemical corrosion
