The Rob Roberts Gun Works RR3 Raptor Optima HP 20 Gauge choke tube is engineered for long-range targets, specifically designed to excel with geese and open water ducks, delivering consistent pattern density when paired with the correct loads. Built from 17-4 PH stainless steel, this choke reflects years of product development and innovations, employing the highest advanced technology available to maximize performance in demanding waterfowl environments. The design features internal cuts that optimize pattern density, helping shooters achieve tighter pellets at extended distances without sacrificing reliability or durability. Note that Over-Schotguns can accommodate a RRaptor choke in only one barrel, as the design does not permit installation in both barrels, making this the ideal choice for hunters seeking a focused, single-barrel performance upgrade. With its robust construction and precision engineering, the RR3 Raptor Optima HP provides predictable, versatile performance across a range of loads, enabling confident long-range shots on geese and open-water ducks while maintaining dependable corrosion resistance and toughness inherent to 17-4 PH stainless steel.
