Carlson's Choke Tubes 59964 Replacement 59964 12 Gauge Modified Flush 17-4 Stainless Steel

The Carlson's Choke Tubes 59964 12 gauge modified flush choke tube is a stainless steel replacement for Browning Invector Plus shotguns. Built from 17-4 heat-treated stainless steel, this flush-mount choke delivers the durability and corrosion resistance serious shooters demand—whether you're running steel, lead, or Hevi-Shot loads through your bird gun. The modified constriction strikes a practical balance between pattern density and shot spread, making it a go-to choice for hunters and sport shooters who want flexibility across a range of distances and game.

Carlson's engineered this tube to handle the rigors of the field without compromise. The stainless construction resists fouling and wear, and the flush-mount design keeps your shotgun's profile clean and snag-free. Whether you're working a duck blind, a turkey roost, or the clay course, a reliable choke tube is foundational to consistent performance.

Since this is a Browning Invector Plus choke, make sure your shotgun uses that system before ordering. Carlson's backs every choke with a lifetime warranty and manufactures them right here in the USA—a promise that stands behind the product for as long as you own it.
