Johnny Stewart
The Johnny Stewart Rob Roberts Gun Works TSS Raptor choke tube is a 20-gauge Invector Plus choke engineered for turkey hunters who demand tight, dense patterns and the reliability of premium materials. Built from 17-4 PH stainless steel, this choke delivers the corrosion resistance and durability serious waterfowl and upland hunters expect in a tube they'll depend on season after season. Whether you're running tungsten-heavy shot loads or traditional TSS ammunition, the Raptor's design is built to maximize pattern performance in 20-gauge shotguns equipped with Invector Plus threads.
The 17-4 PH stainless construction means you're not buying a tube that'll pit or degrade after a few seasons of hunting in wet conditions or salty air. That matters when you're counting on your shotgun to deliver in the moment. The Invector Plus platform is industry-standard on modern Beretta and Benelli shotguns, making this choke a direct fit for a wide range of popular hunting shotguns without any gunsmithing or adapters.
Rob Roberts Gun Works has built a reputation among serious turkey and upland hunters for precision choke engineering, and the TSS Raptor carries that tradition forward. If you're running a 20-gauge and want a choke tube that matches the quality of your gun and ammunition, this is the kind of no-compromise upgrade that pays dividends in the field.

The TSS Raptor is threaded for Invector Plus, the standard choke pattern on modern Beretta and Benelli 20-gauge shotguns. If your shotgun uses Invector Plus threads, it will fit directly. If you're unsure of your shotgun's choke system, check your owner's manual or contact the manufacturer.
This choke is engineered for TSS (tungsten super shot) and tungsten-heavy loads in 20 gauge. It will work with traditional lead or steel shot as well, but it's optimized for premium, denser ammunition.
17-4 PH is a premium stainless alloy that resists rust, corrosion, and pitting far better than standard steel. For a choke tube you'll use in wet hunting conditions and want to last for decades, the material quality directly affects durability and resale value.
