The Johnny Stewart Rob Roberts Gun Works 200142 T2 Triple Threat Invector-DS choke tube is a premium 12-gauge choke designed for shooters who demand versatility and durability in the field. Built from 17-4 PH stainless steel, this tube combines corrosion resistance with the hardness needed to pattern consistently shot after shot, whether you're hunting waterfowl, upland game, or running clays. If your shotgun wears the Beretta/Benelli Invector-DS platform, this choke gives you a serious upgrade over stock tubes.

Rob Roberts Gun Works brings a reputation for precision manufacturing to shotgun chokes, and the T2 Triple Threat line reflects that commitment. The 17-4 PH stainless construction resists rust and pitting even in wet, salty, or heavily-used conditions—a real advantage if you're serious about your shotgun's longevity. The Invector-DS compatibility means this is a direct drop-in for Beretta and Benelli shotguns that use that choke system, no adapters or gunsmithing required.

The "Triple Threat" designation speaks to the tube's ability to handle multiple shooting disciplines. Whether you're patterning for a specific game bird, tightening your spread for distant shots, or fine-tuning your clay target performance, having a quality aftermarket choke gives you tuning flexibility that factory tubes simply don't provide. Stainless steel construction also means you can leave it in the gun without worrying about corrosion or galvanic action on your barrel.
