The Rob Roberts Gun Works 200291 RR1 Raptor Invector 20 Gauge 17-4 PH Stainless Steel is crafted for serious close-range versatility, pairing precision engineering with durable U.S. stainless steel construction. The RR1 choke represents a refined option designed to optimize pattern density when paired with the right loads, delivering consistent performance at practical distances. Built from years of product development and leveraging advanced technology, these choke tubes are machined from 17-4 PH stainless steel to withstand demanding field conditions while maintaining reliable in-barrel performance. Acknowledging practical use, Over-Shotguns can feature a RRaptor choke in only one barrel, as the design does not allow for placement in both barrels, which informs how you set up your shotgun for specific shooting scenarios. This choke tube is designed to integrate smoothly with compatible Invector systems and is ideal for hunters and shooters seeking enhanced close-range effectiveness without compromising durability. With its robust materials and thoughtful engineering, the RR1 Invector 20 gauge choke offers dependable, repeatable patterns that support confident stays and precise follow-up shots in real-world field and range environments.
