Carlsons Choke Tube Flush - Mount 20ga Imp Mod Invector+

The Carlsons Choke Tube Flush-Mount 20ga Imp Mod Invector+ is a precision-engineered choke designed for Browning shotguns and compatible platforms. After decades afield, any experienced waterfowler or upland hunter knows that choke selection directly impacts pattern density, shot string consistency, and ultimately, your success in the field. This improved modified choke strikes the balance serious 20-gauge shooters demand—tight enough for distance work on ducks and geese, yet forgiving enough for close-quarters flushing situations where swing speed matters more than pattern perfection.

Constructed from 17-4 stainless steel, this flush-mount choke tube resists corrosion in wet environments and maintains dimensional stability through thousands of rounds. The .605-inch diameter specifications match Browning's Invector Plus platform precisely, ensuring seamless installation without gaps or wobble that can degrade patterns. Its flush-mount design sits completely within the barrel muzzle, eliminating snag hazards in brush and reducing the profile for transport. Steel shot compatibility—a critical requirement for regulated waterfowl zones—is confirmed, allowing hunters to transition between lead and non-toxic loads without purchasing multiple tubes.

This choke excels for hunters working Browning Invector Plus 20-gauge shotguns in mixed-bag scenarios—early-season doves and pigeons, late-season duck flocks, and flushed upland birds where modified constriction delivers reliable harvests at 30–50 yards. Installation is straightforward: remove the existing choke, align the tube with the barrel's threads, and hand-tighten until snug. Carlsons' reputation for consistent manufacturing means you can depend on predictable patterns without trial-and-error testing on game day. Whether you're refining your gun's versatility or replacing a worn tube, this Invector Plus choke represents proven field performance at a competitive price point.
