The Rob Roberts Gun Works 200305 RR2 Raptor Mobil 12 Gauge 17-4 PH Stainless Steel is built to elevate mid-range shooting performance, pairing the Rob Roberts Gun Works reputation with a precision-engineered choke designed for duck and dove hunting where pattern density and consistency matter. Crafted from 17-4 PH U.S. stainless steel, this choke delivers durable durability and corrosion resistance, while its internal cuts are engineered to produce optimal pattern density when matched with the right loads, helping you achieve reliable pellet distribution at practical hunting ranges. The RR2 design reflects years of product development and innovative tech, ensuring a robust choke that maintains repeatable performance under field conditions. Note that over-shotguns can accommodate a RRaptor choke in only one barrel, as the design does not support dual-barrel placement, making it important to select the appropriate single-barrel configuration for your setup. With a focus on practical field use, this choke stands out for shooters who demand dependable mid-range performance and clear, consistent patterns in demanding duck and dove hunts, backed by durable construction and a true commitment to refined choke technology.
