Johnny Stewart Rob Roberts Gun Works 200291 Rr1 Raptor Invector 20 Gauge 17-4 Ph S/S

The Johnny Stewart Rob Roberts Gun Works RR1 Raptor Invector choke tube is a 20-gauge option built from 17-4 pH stainless steel for hunters and sport shooters who demand durability and reliability in their shotgun setup. Whether you're working through tight cover for upland birds or fine-tuning your pattern at the range, a quality choke tube is fundamental to how your shotgun performs. This Invector-compatible design slides into your 20-gauge barrel to give you the constriction and shot pattern you need for the moment.

Rob Roberts Gun Works has earned respect in the shooting community for precision-engineered choke tubes, and the RR1 Raptor reflects that attention to detail. The 17-4 pH stainless steel construction resists corrosion and handles repeated cycles in the field or on the range without degrading. Stainless steel chokes are particularly valuable for hunters who don't baby their gear—they hold up to moisture, salt spray, and the general punishment that outdoor use brings.

Compatibility with Invector-pattern barrels makes this a straightforward upgrade or replacement if you're working with a shotgun using that standard. The 20-gauge bore means you're outfitting a lighter-recoiling shotgun, common for upland hunting, youth shooters, and anyone who values reduced felt recoil during a full day in the field.

Key Features

• 17-4 pH stainless steel construction resists corrosion and wear
• Invector-pattern compatibility for seamless barrel fit
• 20-gauge bore for upland, sport, and reduced-recoil applications
• Engineered by Rob Roberts Gun Works for precision performance

Frequently Asked Questions

Will this choke tube fit my shotgun?

The RR1 Raptor is designed for 20-gauge shotguns with Invector-pattern choke tubes. Confirm your barrel uses the Invector standard before ordering. If your shotgun uses a different choke pattern, this tube will not be compatible.

What's the advantage of stainless steel for a choke tube?

17-4 pH stainless steel resists rust, corrosion, and pitting from moisture and field use. A stainless tube holds up better over time and across varied hunting conditions—salt spray, wet weather, and seasons of storage—without requiring special maintenance.

Is this suitable for hunting or range shooting?

Yes. The RR1 Raptor works for both hunting applications (upland game, waterfowl, and sport shooting) and target practice where you need a reliable, durable choke. The specific constriction for pattern control depends on the choke designation marked on the tube itself, which will guide your shot selection.
