Johnny Stewart
The Johnny Stewart Rob Roberts Gun Works RR2 Raptor Mobil 20 gauge choke tube is built from 17-4 PH stainless steel—a material choice that prioritizes durability and corrosion resistance in the field. If you're running a 20 gauge shotgun and want a quality aftermarket choke option, this tube delivers the kind of construction you'd expect from a custom gunsmith collaboration.
Rob Roberts Gun Works brings specialized expertise to choke tube design, and this stainless steel construction means you're getting a component that won't rust out after a few seasons in the marsh or upland brush. For 20 gauge shooters who treat their gear seriously, swapping in a precision choke tube can fine-tune your pattern and give you real control over shot placement—whether you're hunting waterfowl, upland birds, or working the range.
Installation is straightforward if you're familiar with your shotgun's threading and choke compatibility. Always verify that your specific 20 gauge is threaded to accept aftermarket chokes before purchasing. If you're unsure, your gunsmith or the shotgun's manual will confirm the specs.

This choke tube is designed for 20 gauge shotguns. Confirm that your shotgun has aftermarket choke threads before ordering.
Stainless steel, especially 17-4 PH, resists rust and corrosion from moisture, powder residue, and outdoor exposure. It's a durable choice for a component you want to last years of regular use.
Not all 20 gauges accept aftermarket chokes. Your shotgun must have threaded choke tubes. Check your shotgun's manual or have a gunsmith verify thread type and pitch before purchasing.
