The JEBS High Voltage choke is built for one thing: putting more pellets on the bird when the shot stretches out there. This is the 20 gauge model with a .590 constriction, threaded for the Benelli/Beretta Mobil system, so it drops right into a good number of popular 20 gauge autos and pumps. JEBS rates the .590 as playing like a Modified, which makes it a versatile all-around choice for ducks over decoys out to birds working the edges.
The magic here is the patented interior bore work (U.S. Patent #8458945) that shortens and tightens the shot string. A shorter shot column means more pellets hit the bird at the same time, which translates to cleaner kills and fewer cripples. It handles just about anything you feed it, whether that's steel, lead, bismuth, hevi-shot, or tungsten, so you're not locked into one load. The tube is CNC machined from 17-4 stainless and heat treated to around 44 Rockwell, which is what lets it stand up to the harder non-toxic loads without getting chewed up.
The black nitride coating isn't just for looks, though it does look sharp sitting flush in the muzzle. That finish adds corrosion resistance and a slick surface that shrugs off the mud, salt, and grime that come with a season of waterfowl hunting. The ported design also helps tame muzzle jump a touch, which keeps you on target for a quick second shot.
Hunters who run these consistently report noticeably denser, more even patterns compared to the factory tubes their guns shipped with. If you're serious about reaching birds at the far end of your effective range with your 20 gauge, this is a proven upgrade worth patterning with your favorite load. Proudly made in the USA out of Hazlehurst, Georgia.
This tube is threaded for the Benelli/Beretta Mobil choke system, which is one of the most common patterns out there. It fits Beretta and Benelli guns that use the Mobil thread, along with Franchi and other shotguns built around that same system. If you're unsure, check your barrel or owner's manual to confirm your gun uses the Mobil pattern before ordering.
JEBS rates the .590 as similar to a Modified choke in 20 gauge. That makes it a flexible all-around pick for waterfowl, tight enough to reach birds working the edges but forgiving enough for decoying ducks at moderate range. As with any choke, pattern it with your specific load to dial in your best effective range.
Yes. The High Voltage tube is machined from 17-4 stainless and heat treated to around 44 Rockwell specifically so it can handle steel, lead, bismuth, hevi-shot, and tungsten loads without damage. That versatility is a big part of why hunters like running one tube for different loads through the season.
Yes, this Black Nitride High Voltage model uses an extended, ported design. The porting helps take a little edge off muzzle jump so you can get back on target faster for a follow-up shot, and the extended length makes it easy to install and remove by hand in the field.
