The Rob Roberts Gun Works RR1 Raptor Invector 12 Gauge 17-4 PH Stainless Steel is engineered for close-range targets, delivering dense, even patterns when paired with the right loads. Built from 17-4 PH U.S. Stainless Steel, these choke tubes result from years of product development and innovations using advanced technology, designed to maintain reliability and durability under field conditions. The RR1 choke features internal cuts that optimize pattern density, helping shooters achieve consistent results at practical distances. Important to note, Over-Shotguns can accommodate a RRaptor choke in only one barrel, as the design does not permit placement in both barrels, ensuring correct fit and performance for single-barrel configurations. This choke is ideal for upland hunting, turkey shoots, and waterfowl scenarios where tight, controlled patterns are essential, and its stainless construction resists wear from repeated use and exposure to the elements. The integration of a high-grade material with precision-cut internal geometry makes it a dependable choice for shooters seeking improved shot distribution without compromising durability or ease of maintenance, aligning with Rob Roberts Gun Works reputation for quality in shotgun parts and accessories.
