Carlsons Choke Tube Flush - Mount 12ga Mod Invector

The Carlsons Choke Tube Flush-Mount 12ga Mod Invector is a precision-engineered replacement choke designed for Winchester shotguns equipped with the Invector choke system. Built for tactical operators, hunters, and competitive shooters who demand reliable pattern consistency and rapid choke changes in the field, this flush-mount modified choke delivers the tight shot patterns required for medium-range precision work. Whether you're running a patrol shotgun, executing tactical drills, or hunting game at distance, a quality choke tube is non-negotiable for optimizing your 12-gauge performance.

Manufactured from 17-4 stainless steel, the Carlsons choke delivers superior corrosion resistance and durability under harsh operational conditions—essential for law enforcement and military applications where equipment must withstand extended storage and variable climates. The flush-mount design minimizes snag hazards and maintains a streamlined profile critical for tactical carbine work and confined-space operations. With a .710-inch diameter specification, this modified constriction produces tighter patterns than improved cylinder or skeet tubes, ideal for precision shooting at 25–40 yards. The choke is certified safe with steel shot, lead, copper-plated, nickel-plated, and Hevi-Shot ammunition, ensuring compatibility across all common ammunition types without bore damage.

This choke tube is purpose-built for Winchester Invector-threaded barrels and installs without tools—a critical advantage during field transitions or pre-mission setup. Tactical teams standardizing shotgun configurations benefit from the interchangeable design, enabling rapid pattern adjustments between close-quarters defense loads and extended-range buckshot drills. Hunters pursuing upland game or waterfowl will appreciate the consistent, predictable patterns the modified constriction provides. The lightweight design (0.2 lbs) adds negligible burden to duty or sport shotguns, and the compact footprint (3.65 x 1.25 x 7.85 inches) fits easily in kit bags or administrative pouches for mission-critical spare tubes.
