Carlsons Choke Tube Flush - Mount 12ga Imp Mod Invector

The Carlsons Choke Tube Flush-Mount 12ga Imp Mod Invector is a precision-engineered choke tube designed for shooters who demand controlled shot patterns and reliable performance in competitive and hunting environments. Built by Carlson, a trusted name in shotgun accessory manufacturing, this improved-modified choke delivers the tight, consistent patterning that serious wingshooters and clay competitors depend on. Whether you're fine-tuning your Winchester-compatible shotgun for duck season or dialing in your pattern for trap shooting, this flush-mount choke offers the versatility and durability required for demanding field work.

Engineered from 17-4 stainless steel, the Carlsons choke tube resists corrosion and maintains dimensional integrity through extended use and exposure to harsh weather conditions. The .705-inch bore diameter is precisely machined to create an improved-modified constriction that bridges the gap between full and modified patterns, providing excellent shot density at mid-range distances—typically 25 to 40 yards depending on ammunition type. The flush-mount design sits seamlessly with the shotgun's muzzle, eliminating snag points and reducing profile for easier gun handling in brush or tight spaces. This tube is safe to use with steel shot, lead, and copper-plated ammunition, giving you flexibility across different hunting seasons and ammunition preferences without requiring barrel changes.

This choke tube is ideal for 12-gauge Winchester Invector-platform shotguns and works best in applications where medium shot concentration enhances accuracy without excessive pellet bunching. Hunters pursuing waterfowl, upland game, and clay target competitors all benefit from the improved-modified pattern this tube delivers. Installation is straightforward—hand-tighten the tube into your shotgun's choke chamber until snug; avoid over-torquing to prevent thread damage. The compact 3.6-inch length and lightweight 0.2-pound design mean minimal impact on muzzle balance or swing characteristics, allowing you to shoot naturally without adapting to added weight or length.
