Johnny Stewart Rob Roberts Gun Works 200301 Rr3 Raptor Invector Plus 20 Gauge 17-4 Ph S/S

The Johnny Stewart Rob Roberts Gun Works RR3 Raptor Invector Plus 20-gauge choke tube is built for shooters who demand durability and precision in the field. Machined from 17-4 PH stainless steel, this tube resists corrosion and maintains its dimensions shot after shot—critical when you're counting on consistent patterns in tight cover or at the range. If your 20-gauge shotgun uses Invector Plus threading, this is the upgrade that bridges aftermarket quality with reliable performance.

Rob Roberts Gun Works has earned a reputation for choke-tube craftsmanship, and the Raptor line reflects that focus. Stainless steel construction means you won't fight rust or degradation from moisture and powder residue, especially important for hunters who shoot in wet conditions or store their guns in challenging environments. The RR3 profile is designed to deliver the shot pattern you expect without surprises.

Upgrading from factory tubes or worn originals pays dividends in tighter groupings, more predictable patterns, and gear that lasts. Whether you're working upland birds, waterfowl, or clay targets, a quality choke tube is one of the easiest ways to refine your gun's performance without major investment.
