Johnny Stewart Rob Roberts Gun Works 200297 Tss Raptor Invector Plus 12 Gauge 17-4 Ph S/S

The Johnny Stewart Rob Roberts Gun Works TSS Raptor Invector Plus choke tube is a 12 gauge option built for serious turkey hunters and high-performance shotgun shooters. This Invector Plus choke delivers the density and pattern control you need when you're running tungsten super shot (TSS) loads—ammunition that demands a precision choke engineered to handle the hard, heavy pellets without deformation or erratic patterns.

Built from 17-4 stainless steel, this choke resists corrosion and wear from repeated shooting sessions and harsh field conditions. The 17-4 PH material is known for its toughness and durability, making it a solid choice if you're running premium ammunition and expect your gear to perform consistently over years of use. The stainless construction also means minimal maintenance and a choke that won't rust or degrade between seasons.

If you're shooting an Invector Plus shotgun and chasing tight patterns with modern TSS turkey loads, this Rob Roberts Gun Works choke is purpose-built to maximize what those premium pellets can do. It threads into any Invector Plus barrel, so compatibility is straightforward as long as your gun uses that system.

Specifications

Frequently Asked Questions

Will this choke fit my shotgun?

This is an Invector Plus choke, so it will only fit shotguns with Invector Plus threading. If your 12 gauge shotgun uses Invector Plus chokes (common on Browning and compatible models), this choke will thread in directly.

Can I shoot regular shotgun ammunition through this choke?

The choke is specifically engineered and optimized for tungsten super shot (TSS) loads. While it will accept other ammunition, it's built and tuned to perform best with TSS pellets.

Why does this choke cost more than standard chokes?

This is a specialized choke designed for premium tungsten super shot ammunition. The 17-4 stainless steel construction and Rob Roberts Gun Works tuning for TSS patterns add to the cost, but the durability and performance with high-end turkey loads justify the investment for serious hunters.
