Carlsons Choke Tube Flush - Mount 12ga X-full Invector

The Carlsons Choke Tube Flush-Mount 12ga X-Full Invector is a precision shotgun choke engineered for hunters and tactical operators demanding consistent, tight patterns at extended ranges. This extra-full choke tube delivers the constriction needed for steel shot restrictions and lead ammunition applications where maximum shot density is critical. Built to Winchester Invector specifications, the flush-mount design integrates seamlessly with modern shotgun platforms while maintaining the aerodynamic profile essential in tactical environments.

Manufactured from 17-4 stainless steel, this choke tube withstands repeated cycling and corrosive field conditions without degradation—a critical consideration for law enforcement and military personnel operating in saltwater or harsh climates. The .690-inch diameter provides the extra-full constriction that concentrates pellet energy downrange, reducing spread and improving accuracy beyond 40 yards. The flush-mount design eliminates external protrusion, reducing snag hazards during tactical movement and breaching operations. This construction method ensures zero reliability compromise while maintaining the compact profile shooters demand from modern combat shotguns.

This choke excels for shooters using lead shot in hunting or sport applications where dense patterns improve ethical kills on game at distance. Tactical teams utilize extra-full chokes to maximize lethality and minimize collateral spread in entry scenarios. Quick-change compatibility with Invector-compatible platforms—including Browning, Mossberg, and Winchester models—makes field adaptation practical without gunsmithing. Installation requires only hand-tight insertion into the choke tube seat; remove before storage and apply light lubricant to prevent corrosion. Note that this choke is not rated for steel shot, making it unsuitable for waterfowl applications requiring non-toxic ammunition.
