Johnny Stewart T3 Triple Threat Invector-DS 12 Gauge Choke Tube - 17-4 PH Stainless Steel

The Johnny Stewart T3 Triple Threat is a precision-machined 12 Gauge choke tube built for shotguns fitted with the Invector-DS choke system. Manufactured by Rob Roberts Gun Works from rugged 17-4 PH stainless steel, it is engineered for dependable patterning across the full range of shotgunning applications.

The T3 sits at the top of the Triple Threat choke family, a line developed for clay shooters, upland hunters, and waterfowl hunters who want consistent, repeatable patterns. The Invector-DS threading mates precisely with compatible Browning barrels, and the stainless construction is rated safe with steel shot, exotic non-toxic shot, and conventional lead loads, giving shooters the freedom to match the choke to any quarry or sporting-clays course.

Installation is straightforward: remove the existing choke, drop the T3 into the muzzle, and thread it down to spec using the appropriate choke wrench. Once seated, the choke delivers tight, even patterns, making it a versatile choice for upland fields, waterfowl marshes, and the sporting clays course alike.
