Winchester Signature Invector Plus 12 Gauge Extra Full Extended Choke Tube - 17-4 Stainless Steel

The Winchester Signature Invector Plus extended choke tube delivers consistent, uniform shot patterns for serious 12 Gauge shotgun shooters. Built from durable 17-4 stainless steel with a bright stainless finish, this choke is engineered for long-range work with an Extra Full constriction of .040" and a recommended engagement distance of 45+ yards.

Designed as part of Winchester's Signature Series, this tube features the extended-length profile that projects the constriction beyond the muzzle to tighten pattern density downrange. It is approved for lead shot only and is purpose-built for trap and other multi-purpose shotgunning applications where concentrated, predictable patterns are critical.

The Invector Plus choke system is fully compatible with current and past Winchester shotguns chambered for the Invector Plus standard, including the Model 101, Supreme, Select, SX2, SX3, SX4, and SXP. Installation is straightforward: thread the tube into the muzzle and tighten by hand or with the appropriate choke wrench. One choke tube is included.
