Description
The JEBS High Voltage Choke Tube in .690 is a waterfowl tube made to fit the Retay MaraPro choke system found on Masai Mara, Gordion, and other Retay 12 gauge shotguns. It carries a matte stainless finish and a ported design, and it's the one a lot of duck and goose hunters reach for when they want tight, consistent patterns without babying their loads. This one runs steel, lead, bismuth, or the newer hybrid loads, so you're not locked into a single shell type.
What the .690 High Voltage Does on the Water
At .690, this sits in that sweet spot JEBS describes as long to mid-range depending on your shot size. Run bigger pellets like BB, BBB, or #2 and it patterns closer to a long-range tube, reaching ducks that flare off before they commit. Drop down to smaller steel and it opens up into more of a mid-range spread for decoying birds. That flexibility is a big reason folks keep buying these for multiple guns. Real-world feedback from hunters running it on guns like the Browning A5 and Auto 5 points to even, killer patterns across everything from #5 bismuth to #2 steel.
Porting and Build on the High Voltage Tube
The ports up top vent gas to help settle muzzle rise and take some sting out of felt recoil, which matters on those mornings when the birds keep working and you're burning through heavy 3-inch loads. Machined from stainless with a matte finish, it shrugs off the wet, muddy abuse that comes with a duck blind. The patented JEBS design is what drives the shortened, denser shot-stream that gives this tube its knock-down reputation on longer shots.
One thing worth flagging: double-check that your barrel uses the Retay MaraPro thread pattern before ordering, since it's semi-proprietary and shares looks with the Benelli Crio Plus without being a guaranteed swap. Made in the USA in Hazlehurst, Georgia.

Frequently Asked Questions
Will this JEBS High Voltage choke tube fit my Retay shotgun?
This tube is cut for the Retay MaraPro choke pattern used on most Retay 12 gauge shotguns like the Masai Mara and Gordion. The MaraPro thread looks like a Benelli Crio Plus but the thread and collar diameters are smaller, so it isn't a guaranteed cross-fit. Check your barrel's choke system before ordering to be sure it matches.
Can I shoot steel, bismuth, and lead through the .690 High Voltage?
Yes, the High Voltage series is designed to handle steel, lead, bismuth, or other shot types without you needing to swap tubes. That versatility is one of its main selling points for waterfowl hunters who run different loads through the season. Hunters report clean, even patterns with everything from #5 bismuth to #2 steel.
What range is the .690 constriction best for?
JEBS rates the .690 as a long to mid-range tube, and the effective range shifts with your shot size. Larger pellets like BB, BBB, or #2 pattern more like a long-range choke for birds that hang up, while smaller steel opens into a mid-range spread for decoying ducks. It's a solid all-around pick for pass shooting and over-the-decoy work alike.
Does the porting really help with recoil?
The ports vent gas near the muzzle, which helps tame muzzle rise and cut down on the felt recoil from heavy waterfowl loads. On long mornings running 3-inch shells that adds up to a more comfortable day in the blind. It also keeps you back on target quicker for follow-up shots.
