The Rob Roberts Gun Works RR3 Raptor Invector 20 Gauge 17-4 PH Stainless Steel is engineered for long-range targeting and waterfowl success, with a design specifically tailored for geese and open water ducks. This choke tube delivers optimal pattern density when paired with the right loads, a testament to years of development and innovative thinking using the highest-grade technology available. Constructed from 17-4 PH U.S. stainless steel, it combines corrosion resistance with dependable performance in demanding field conditions. While the RR3 performance shines in a single-barrel setup on Over-Under configurations, keep in mind that the RRaptor choke is designed for placement in only one barrel, reflecting thoughtful engineering to maximize effectiveness without compromising reliability. The result is a durable, precision-focused choke that supports consistent, bake-forged patterning at practical hunting distances, enabling shooters to place shots with confidence on waterfowl scenarios. For hunters seeking a purpose-built solution that aligns with long-range tendencies and the needs of geese and open-water ducks, this Invector-compatible choke from Rob Roberts Gun Works offers a refined balance of material quality, design intent, and field-proven performance.
