The Carlson's Choke Tubes 17799 Buckshot delivers a precision-engineered 12 gauge extended choke crafted from 17-4 stainless steel with a durable black finish, designed to optimize buckshot patterning and performance for field or range use. This Invector-compatible choke features a ported design with a .700 constriction diameter, providing enhanced recoil management and improved muzzle control while maintaining reliable performance with steel, lead, and non-toxic loads. Built from high-grade stainless steel, the 17-4 composition ensures corrosion resistance and long-term durability under demanding conditions, making it a practical choice for hunters and shooters who demand consistency across multiple outings. The included extended choke length contributes to a tighter, more uniform shot string, while the porting helps reduce muzzle rise for faster follow-up shots. Ideal for Winchester 12 gauge platforms, this Carlsons choke tube is suited for buckshot applications where reliable pattern density and control are essential. With a black finish that resists wear and a robust construction, it stands up to rugged field use and ensures repeatable performance when precision matters most.
