Johnny Stewart RR1 Raptor Invector 20 Gauge 17-4 PH Stainless Steel Choke Tube

The Johnny Stewart RR1 Raptor is a premium 20 Gauge shotgun choke tube engineered for close-range targets where dense, consistent patterns matter most. Built by Rob Roberts Gun Works and machined to tolerances well beyond typical industry standards, the RR1 is part of the Raptor series of precision chokes designed for hunters who demand reliable pattern performance from their shotgun.

Constructed from 17-4 PH U.S. stainless steel, the RR1 is built for durability and corrosion resistance in the field. It is designed as a direct fit for shotguns equipped with the standard Invector choke system (not Invector Plus), making it a drop-in upgrade or replacement for factory tubes on compatible 20 Gauge shotguns.

Rob Roberts Gun Works produces each Raptor-series choke using state-of-the-art equipment backed by computerized pattern analysis. The RR1's internal cuts are optimized to deliver a tight, dense core pattern at close range, pairing especially well with the appropriate load selection for turkey hunting, upland birds, or any close-quarters shotgunning application. The choke is backed by the Johnny Stewart brand's reputation for quality hunting accessories.
