Carlson's Choke Tubes 59966 Replacement 59966 12 Gauge Full Flush 17-4 Stainless Steel

The Carlson's 12 Gauge Full Flush Choke Tube in 17-4 stainless steel is a durable replacement choke for Browning Invector Plus shotguns. Built from heat-treated stainless steel, this full constriction choke delivers the tight, consistent patterning you need for precision shotgun work—whether you're chasing waterfowl, upland birds, or clay targets. The flush-mount design seats cleanly in your shotgun's receiver for a sleek profile and easy installation. Made in the USA and backed by Carlson's Lifetime Warranty, it's the kind of workhorse upgrade that outlasts the gun it's threaded into.

Versatility matters in the field. This choke handles steel shot, lead, and Hevi-Shot ammunition across its full constriction, giving you flexibility to load what works for your hunting or shooting situation. Just follow Carlson's guidelines: no steel shot larger than #BB or velocities over 1550 fps in full constriction, and no steel larger than #4 in turkey-specific tubes. That discipline keeps your barrel safe and your patterns true.

If you run a Browning Invector Plus shotgun, this is a straightforward upgrade that takes minutes to swap in. No gunsmithing, no special tools—just unscrew, thread on, and get back to the range or the blind. The stainless construction resists corrosion, so it'll handle moisture, salt air, and hard use without degrading. A single quality choke tube is the kind of sensible investment that pays for itself in better patterns and years of reliable service.
