The Johnny Stewart Rob Roberts Gun Works RR1 Raptor Invector 12-gauge choke tube delivers a durable, precision-engineered solution for shooters who demand reliable performance and longevity. Machined from 17-4 PH stainless steel, this choke tube resists corrosion and wear—critical when you're running thousands of rounds through your shotgun or when salt spray and moisture are part of your hunting or clay-shooting routine. Built for Invector-compatible shotguns, the RR1 Raptor is the choice for hunters and shooters who want aftermarket choke quality without the guesswork.

Rob Roberts Gun Works has earned a reputation for precision shotgun work, and this choke tube reflects that craftsmanship. The 17-4 PH stainless construction means you're getting a material known for strength and corrosion resistance—not a softer steel that will degrade season after season.

If you run an Invector-threaded shotgun and are tired of settling for mediocre factory chokes, this is a legitimate upgrade. The RR1 Raptor is engineered to last and perform, backed by a builder whose name means something in the shotgun community.
