Our signature tube with the signature red band on the front of the tube plus a knurled finger surface.
A little longer for a bit more performance. The Signature Series of Winchester Invector Plus choke tubes are made to bring out the performance of your shotgun. The extended length, combined with perfected choke tapers create a consistent, reliable, uniform pattern at each constriction. Signature Series tubes are available in full range of constrictions for optimizing your pattern for the game or target you are shooting. These choke tubes are 12 Gauge only for current and past Winchester shotguns: Model 101, Supreme, Select, SX2, SX3 and SXP shotguns.
A few details. The proven Invector-Plus interchangeable choke tube system works hand-in-hand with back-boring to offer consistent, dense shot patterns with the ideal tube constriction needed for the shooting situation. The longer choke taper inside an Invector-Plus choke tube produces consistent patterns with more uniform densities and fewer fliers. The superior design of the Invector-Plus system is far more durable than the choke systems found in our competitors’ guns, especially when shooting steel shot. Invector-Plus eliminates gases slipping between the choke tube and barrel that could damage the choke tube and the barrel.
