Description
The Jeb's High Voltage Ported Choke Tube is a purpose-built waterfowl choke for the 12 gauge Beretta A400 Optima H.P., machined with a .695 constriction that lands in the improved range on Jeb's system. That opening is a favorite for decoying ducks and geese in that middle 25 to 40 yard window, where you want a pattern that stays dense enough to fold birds cleanly but isn't so tight it turns close shots into a coin flip. The whole idea behind the High Voltage line is a patented internal geometry that gives you a shortened, more distinct shot-stream and repeatable patterns, which is what puts pellets on target when a bird flares late.
What Sets the High Voltage Tube Apart
Jeb's builds these from 17-4 stainless heat treated to around 44 Rockwell, and that matters more than it sounds. That hardness is what lets a single choke chew through steel, lead, bismuth, and tungsten loads without wearing out or getting chewed up by hard shot. You're not stuck buying a different tube for every ammo type, which is a real perk when steel and bismuth prices have you experimenting with what patterns best out of your gun.
Porting on Your A400 Setup
The ported design vents gas up top as the wad clears the muzzle, which takes some of the edge off felt recoil and helps keep the muzzle settled for a faster second shot. On a gas-operated A400 that's already soft-shooting, the payoff is a rig that stays flat and lets you get back on a follow-up bird in a hurry. Fit is dialed for the Beretta Optima H.P. thread pattern, so it seats flush and true without any fuss.
Bottom line, this is a workhorse tube for the duck blind or goose spread. Pattern it with your go-to load before the season, note where the sweet spot lands, and you'll have a good read on your effective range come opening day. Made in the USA.

Frequently Asked Questions
What choke does the .695 constriction compare to on the Jeb's High Voltage tube?
On Jeb's own scale, the .695 falls into the improved range, which is a bit more open than a standard modified. It's a solid pick for decoying ducks and geese in the mid-range where you want a full, forgiving pattern. If you're consistently reaching for longer shots, a tighter constriction may pattern better for you.
Will this Jeb's High Voltage choke handle steel and bismuth shot?
Yes. It's machined from 17-4 stainless heat treated to about 44 Rockwell, which is hard enough to run steel, lead, bismuth, and even tungsten loads. That means one tube covers just about any waterfowl load you want to throw at it.
Does the porting really make a difference on a Beretta A400?
The porting vents gas as the shot clears the muzzle, which trims felt recoil and helps keep the barrel from rising. On the already soft-shooting gas-operated A400, it makes getting back on a second bird noticeably quicker.
Which Beretta shotguns does this choke fit?
This tube is cut for the Beretta A400 Optima H.P. thread pattern. It won't fit older Beretta Mobil-choke guns, so double-check that your A400 uses the Optima H.P. system before ordering.
