Johnny Stewart Rob Roberts Gun Works 200132 T3 Triple Threat Invector Plus 20 Ga 17-4 Ph

The Johnny Stewart Rob Roberts Gun Works T3 Triple Threat choke tube for 20-gauge shotguns gives you a reliable, durable option for tuning your shot pattern. Built from 17-4 PH stainless steel, this choke is designed to work with Invector Plus compatible shotguns—the standard tube system found on many modern Browning and Beretta 20-gauge shotguns. Whether you're hunting upland game, working clay targets, or testing different constriction patterns at the range, a quality aftermarket choke lets you dial in the performance your load and distance demand without swapping guns.

Stainless steel construction resists corrosion and wear, so you'll have a choke tube that holds up to repeated use and cleaning. The Triple Threat designation suggests this tube is engineered for versatility across hunting and sport-shooting applications. For 20-gauge shooters who already trust their gun's handling and ergonomics but want to experiment with tighter or more open patterns, a dedicated choke tube is one of the most cost-effective upgrades available.

Rob Roberts Gun Works has built a solid reputation for quality shotgun components and custom work. This choke brings that craftsmanship to an accessible price point, making it a solid choice if you're tired of being locked into your gun's factory tube or looking to keep a spare on hand for different hunting situations.
