Johnny Stewart Rob Roberts Gun Works 200293 Rr3 Raptor Invector 20 Gauge 17-4 Ph S/S

The Johnny Stewart Rob Roberts Gun Works RR3 Raptor Invector choke tube is a premium 20-gauge shotgun choke built for hunters and clay shooters who demand durable, precision-engineered performance. This 17-4 PH stainless steel choke tube delivers the corrosion resistance and strength you need whether you're working through wet brush, coastal salt spray, or spending long days at the range. Rob Roberts Gun Works' reputation for quality machining shines through in a tube designed to handle repeated use and harsh field conditions without degradation.

Designed specifically for Invector-equipped 20-gauge shotguns, the RR3 Raptor offers a purpose-built solution if your gun's choke system demands a tube that won't let you down. The stainless steel construction resists rust and pitting far better than standard steel, a real advantage if you hunt wet country or store your gun in less-than-ideal conditions. This is the kind of solid, uncompromising hardware you expect from a custom gunsmith shop—not flashy, just reliable.

Whether you're fine-tuning your 20-gauge's shot pattern for upland birds, waterfowl, or clays, a quality choke tube is a small investment that pays dividends in consistency and longevity. If you already run an Invector system, the RR3 Raptor is worth a close look.
