Description
When the birds start decoy-shy and you're stretching your shots, this is the choke you want threaded into your 20 gauge Benelli. The Carlson's Delta Waterfowl Extended is the Long Range tube with a .595 constriction, meaning it squeezes your pattern down hard for those birds hanging out on the edge of range. It drops right into Benelli shotguns running the Crio and Crio Plus choke system.
Carlson's machines these from solid 17-4 stainless steel, the same corrosion-resistant material they use across their steel shot lineup, which matters when you're standing in a wet blind at dawn. The knurled extension sticks out about 3/4 inch past the muzzle, giving you a spot to grip for quick swaps and helping protect your barrel threads from the pounding of heavy steel loads. The constriction and size are laser marked right on the tube, so you'll never be guessing which one you pulled out of the bag.
What the .595 Long Range Delta Waterfowl Tube Does Best
The real story here is the longer parallel section. Compared to a factory tube, this design runs a noticeably longer straight section that lets the shot settle before it leaves the barrel, and that translates to denser cores and fewer stray pellets flying off the edge of the pattern. For pass shooting and finishing birds at distance, that tighter pattern is exactly what puts more pellets on target.
Getting the Most Out of Your Delta Waterfowl Long Range Choke
Since this is the tightest tube in the family, keep your steel shot to BB or smaller and stay under 1550 fps through the Long Range constriction. Faster or bigger steel loads are better run through a more open tube. And like any choke, pattern it with the exact shell you plan to hunt before opening day. Different loads throw different patterns from the same tube, so a little time at the board pays off when it counts. It's backed by Carlson's lifetime warranty and made in the USA.

Frequently Asked Questions
What shotguns does this Delta Waterfowl choke tube fit?
It's built for 20 gauge Benelli shotguns that use the Crio and Crio Plus choke system. If your Benelli takes Crio/Crio Plus tubes, this one threads right in. Always double-check your barrel's choke system before ordering.
Can I run steel shot through the .595 Long Range tube?
Yes, these tubes are designed to pattern steel shot well. Just keep your steel to BB size or smaller and stay under 1550 fps through this Long Range constriction. Larger or faster steel loads should go through a more open tube like the Mid Range.
How is the Long Range different from the Mid Range Delta Waterfowl tube?
The Long Range .595 is the tighter of the two, squeezing your pattern down for birds at the far end of your effective range. The Mid Range opens things up a bit for closer decoying work and handles a wider variety of steel loads. Most waterfowlers like having both on hand to match the day's shooting.
Why does this choke stick out past the barrel?
The extended design puts the knurled end roughly 3/4 inch past your muzzle, which gives you a grippy surface for quick tool-free swaps in the blind. It also helps protect your barrel threads from the wear of repeated heavy steel shot loads.
