Carlsons Choke Tube Flush - Mount 20ga X-full Invector

The Carlsons Choke Tube Flush-Mount 20ga X-Full Invector is a precision shotgun choke engineered for serious wingshooters and tactical operators who demand tight, consistent patterns at extended ranges. Purpose-built for Winchester Invector-compatible shotguns in 20 gauge, this extra-full choke delivers the density and reliability required in competitive shooting, hunting, and duty applications where tight grouping separates success from failure.

Manufactured from 17-4 stainless steel, the Carlsons choke tube features a .585-inch diameter bore and flush-mount design that sits seamlessly at the muzzle end, eliminating snag points and maintaining firearm aesthetics. The extra-full constriction concentrates pellet patterns for maximum payload density downrange, ideal for distant targets and precision shooting scenarios. Stainless steel construction resists corrosion and maintains dimensional stability through repeated use and cleaning, critical for shooters operating in harsh environments or high-volume training cycles. This choke is engineered for lead shot only and is not compatible with steel shot, a critical limitation that must be respected to maintain tube integrity.

Operators running Winchester Invector-threaded 20 gauge shotguns—from Mossberg to Browning platforms—will find drop-in compatibility and immediate performance gains. Installation requires only hand-tight seating into the existing Invector choke port; no tools or gunsmithing required. The flush-mount profile makes this choke ideal for tactical rifle-length shotguns where exposed choke tubes create snag hazards, while competitive shooters benefit from the pattern control at 40-plus yards. Law enforcement and military professionals using 20 gauge platforms for breaching or precision work will appreciate the reliability and repeatability this stainless steel tube delivers under duty conditions.
