The Rob Roberts Gun Works RR1 Raptor Mobil 20 Gauge choke is the premium choice for close-range targets, delivering dense, reliable patterns when paired with the correct loads. The internal cuts are engineered from years of product development and innovations, optimized to maximize pattern density while maintaining durability, and are crafted from 17-4 PH U.S. stainless steel to resist wear and corrosion under demanding field conditions. Designed to work with 20 gauge systems, this choke tube combines advanced technology with practical field performance, helping shooters achieve consistent results on game or targets at short distances. The RR1s precision machining and stainless construction ensure a smooth fit and dependable performance, backed by Rob Roberts Gun Works reputation for quality engineering. Its important to note that Over-Shotguns can accommodate a RRaptor choke in only one barrel, and the design does not allow placement in both barrels, which informs the setup choices for multi-barrel configurations. Masterful in both construction and function, this choke tube enables confident, repeatable patterns in close-quarters shooting while leveraging the strength of 17-4 PH stainless steel.
