Description
This 2-pack pairs a mid-range and a long-range choke into one set, so you can match your constriction to the shot instead of guessing. The mid-range tube shines in that 25-to-40 yard window when birds are working the decoys, while the long-range tube tightens things up for the passing shots and the birds that hang back. Both are cut for Winchester-style threading, the same pattern used on Browning Invector, Mossberg 500, Weatherby, and pre-1993 Ruger Red Label guns. Note that Winchester SX-2, SX-3, and SXP shotguns use Browning Invector Plus tubes instead.
What Sets These Delta Waterfowl Tubes Apart
Carlson's machines these from 17-4 stainless steel, which holds up to wet blinds, salt marshes, and season after season of steel shot without complaint. The real story is inside the tube. A parallel section about 25 percent longer than a standard choke gives the shot column more time to settle before it leaves the muzzle, and that translates to more consistent patterns with fewer flyers downrange.
Built for a Steady Diet of Steel
Steel shot runs through these with excellent results, which is exactly what you want out of a waterfowl choke. One thing worth remembering with the long-range tube: keep steel to BB size and under, and stay below 1550 FPS. If you're running bigger, faster loads, drop in the mid-range tube instead and let it do the heavy lifting.
Small Details That Earn Their Keep
The extended design sits proud of the barrel and is knurled at the end, so swapping tubes in the field is a quick hand-twist with no wrench required. Each one is laser-marked with its constriction and size right on the body, so there's no squinting or guessing which tube you grabbed. Carlson's backs the set with a lifetime warranty, and a slice of every Delta Waterfowl purchase goes toward duck and habitat conservation.

Frequently Asked Questions
Will these Delta Waterfowl choke tubes fit my shotgun?
They're threaded for the Winchester choke pattern, which is shared by Browning Invector (Standard), Mossberg 500, Weatherby, and pre-1993 Ruger Red Label shotguns. If you shoot a Winchester SX-2, SX-3, or SXP, those guns use Browning Invector Plus tubes instead, so this set won't fit them. When in doubt, check the markings on your existing choke tubes or barrel to confirm the thread pattern.
What's the difference between the mid-range and long-range tube in this set?
The mid-range tube is tuned for shots roughly 25 to 40 yards out, ideal for birds working close over the decoys. The long-range tube tightens the pattern for the longer pokes and the birds that hang on the edge. Having both lets you match the choke to the situation rather than compromising with a single constriction.
Can I shoot steel shot through these choke tubes?
Yes, that's exactly what they're built for and they pattern steel very well. With the long-range tube, keep your steel shot at BB size or smaller and stay under 1550 FPS. If you're running larger or faster steel loads, switch to the mid-range tube instead.
Do I need a wrench to install these Delta Waterfowl tubes?
No wrench needed. The extended design sticks out past the muzzle and the end is knurled, so you can hand-tighten and remove them right in the blind. Each tube is also laser-marked with its constriction and size for quick identification.
