The Rob Roberts Gun Works 200316 RR3 Raptor Optima HP 12 Gauge 17-4 PH Stainless Steel choke delivers long-range performance for serious geese and open water duck hunters, combining precision engineering with durable stainless construction to maximize pattern density when paired with the right loads. Crafted from 17-4 PH U.S. Stainless Steel, this shotgun choke tube embodies durability and corrosion resistance while leveraging internal cuts designed to optimize pellet dispersion for extended-range shots. The RR3 design reflects years of product development and innovative thinking, offering consistent, tight patterns at distance without sacrificing load versatility. Ideal for shooters seeking enhanced long-range target acquisition, the RR3 is specifically tuned for geese and open water duck scenarios, helping you achieve reliable impact zones across the water. Note that Over-Shotguns can feature a RRaptor choke in only one barrel, as the choke design does not permit placement in both barrels. With its blend of rugged stainless steel construction, strategic internal geometry, and targeted performance characteristics, this choke tube is a compelling choice for shotgun enthusiasts aiming to improve long-range pattern density and target acquisition in demanding waterfowl environments.
