Description
The Jeb's High Voltage Ported Choke Tube is a waterfowl hunter's answer to birds that just won't commit. Built for the Mossberg 835 and 935 choke system with a .690 constriction, it's engineered to tighten up your pattern and stretch your practical range when the shots keep pushing past comfortable decoy distance. Jeb's patented design produces a more consistent shot pattern and a shortened, distinctive shot-stream, which is exactly what you want when a wad of steel has to hold together long enough to reach a passing flock.
This tube is machined from 17-4 stainless steel and heat treated to 44 Rockwell hardness, so it stands up to steel, lead, bismuth, tungsten, and just about anything else you feed through it. The .690 constriction lands in that sweet range where it behaves like a long-range tube with bigger shot such as BB and BBB, while smaller shot sizes pattern more like a mid-range choke. Whether you're throwing #2 steel over a flooded rice field or reaching for something denser, this constriction gives you flexibility across loads without swapping tubes constantly.
Why the Ported Setup on This High Voltage Tube Matters
The ported configuration vents gas at the muzzle, which helps settle the shot-stream and take a little edge off felt recoil after a long morning in the blind. Hunters running the .690 in Mossberg pumps and autos consistently report even, killer patterns that reach out when ducks hang up just outside easy range. Made in the USA and covered under U.S. Patent #8458945, this is a tube built by folks who take their waterfowl gear seriously.
Getting the Most From Your Jeb's High Voltage Choke
Like any choke, it pays to pattern it on paper with the exact loads you plan to hunt before opening day. Every barrel and shell combo behaves a little differently, and a few minutes at 30 to 40 yards will tell you exactly what this tube is doing downrange. Once you dial it in, it's a set-it-and-forget-it upgrade over the factory tube that came with your gun.

Frequently Asked Questions
Will this Jeb's High Voltage choke fit my Mossberg 935?
Yes. This tube is cut for the Mossberg 835 and 935 choke thread pattern, which are the same system. As long as your barrel uses the standard Mossberg 835/935 interchangeable tubes, this one will thread right in.
Can I shoot steel shot through the .690 High Voltage tube?
Absolutely. It's made from 17-4 stainless heat treated to 44 Rockwell specifically so it can handle steel, lead, bismuth, and tungsten loads. It's built for the harder, faster steel that most waterfowl hunters run these days.
What kind of range does the .690 constriction give me?
The .690 sits in a versatile spot that acts like a long-range choke with bigger shot like BB and BBB, and more like a mid-range tube with smaller shot. Real-world users report clean, dense patterns that reliably reach ducks and geese hanging up around 30 to 45 yards. Pattern it with your actual load to confirm your best distance.
Is the ported design worth it over a non-ported tube?
The porting vents gas at the muzzle to help stabilize the shot-stream and knock down a bit of felt recoil, which is nice over a full day of shooting. It's the setup a lot of serious waterfowlers prefer. For most duck and goose hunting, the ported version is a solid choice.
