Johnny Stewart Rob Roberts Gun Works 200289 Tss Raptor Invector 20 Gauge 17-4 Ph S/S

The Johnny Stewart Rob Roberts Gun Works TSS Raptor choke tube is a specialized 20-gauge tube built for serious turkey hunters and waterfowl shooters who demand premium shot patterning and durability. Crafted from 17-4 PH stainless steel, this tube handles the corrosive nature of steel and TSS (Tungsten Super Shot) loads without pitting or degradation—a critical advantage when running modern non-lead ammunition through your shotgun repeatedly. The Invector compatibility means it threads directly into Invector-platform shotguns, making it a straightforward upgrade for hunters who already own a compatible 20-gauge.

Rob Roberts Gun Works is known for precision choke work, and this TSS Raptor is designed around the specific demands of today's premium shotgun loads. TSS ammunition patterns tighter and cleaner than traditional shot, and a dedicated choke tube maximizes that advantage. Whether you're hunting turkeys in spring or working waterfowl in fall, the stainless construction ensures the tube won't corrode or gum up over seasons of use—especially important if you're running lead-free loads in harsh weather.

Installation is simple: unscrew your current choke and thread this one in by hand until snug. Keep it with your 20-gauge for your go-to application, and you'll have a choke built specifically for the ammunition and hunting you care about most.

Frequently Asked Questions

What shotguns does this choke tube fit?

The TSS Raptor is compatible with 20-gauge shotguns using the Invector choke system. Confirm your shotgun has an Invector threaded barrel before purchasing.

Can I use this with steel shot and non-lead ammunition?

Yes. The 17-4 PH stainless steel construction is specifically designed to withstand corrosion from steel shot and tungsten-based TSS loads, which are more corrosive than lead. This tube handles modern non-lead ammunition reliably.

Is this choke optimized for turkey or waterfowl hunting?

The TSS Raptor design is optimized for TSS loads, which are commonly used in turkey hunting for superior pellet density and patterning. It will also work with waterfowl loads, but was engineered with premium turkey ammunition in mind.

How do I install this choke tube?

Remove your current choke by hand (unscrew it) and thread the TSS Raptor into the Invector port until snug. Do not over-tighten. Installation requires no special tools.
