Description
The Salvo 12 mounts differently than a rifle can. There's no muzzle thread or clamp involved. Instead, it hangs off your shotgun's choke threads, and that means you need the correct Echo choke adapter for your specific barrel. This one, the AC1326, is built for Beretta and Benelli Mobil pattern chokes, which covers a huge range of guns from the Beretta A300 and 390 family to Benelli models running the Mobil system. If you're not sure which choke pattern your barrel uses, check your factory chokes or your owner's manual before ordering, because Mobil and Crio threads are not interchangeable.
How the Echo Choke Adapter Works
Installation is about as simple as it gets. Pull your factory choke, thread the Echo adapter in its place, and you're left with an external locking ring that the Salvo 12 attaches to. The connection is solid and repeatable, so you can pull the can off for a normal day of shooting and put it back on without chasing your zero point of impact all over the pattern board. The adapter itself is steel with a black finish, and it only adds a couple tenths of a pound to the end of your barrel.
Full Choke Constriction, Suppressor Ready
This version carries a Full constriction, so you keep the tight, dense patterns you'd want for turkey hunting, longer passing shots on waterfowl-style ranges with appropriate loads, or trap work. That's one of the smarter parts of the Echo system: you're not giving up choke performance to run suppressed. Two things worth knowing before you load up, though. Steel shot should not be run through a Full constriction, so stick with lead or other soft shot in this one. And the Salvo system doesn't play well with flight-controlled wads, so choose your shells accordingly.
Pairing the AC1326 with Your Salvo 12
SilencerCo makes Echo adapters in Improved Cylinder, Improved Modified, and Full for the Mobil pattern, so a lot of Salvo owners keep two or three on hand and swap constrictions the same way they'd swap chokes. If Full is your go-to, this is the one to grab for your Mobil-threaded Beretta or Benelli.

Frequently Asked Questions
Will the Echo choke adapter AC1326 fit my shotgun?
This adapter fits barrels threaded for the Beretta/Benelli Mobil choke pattern, which is common on many Beretta autoloaders and Benelli shotguns that don't use the Crio system. Mobil and Crio threads look similar but are not interchangeable, so verify your choke pattern before ordering. If your gun runs Crio or Crio Plus chokes, you'd want the AC1325 instead.
Do I need this adapter to mount the Salvo 12?
Yes. The Salvo 12 doesn't thread onto a muzzle device like a rifle suppressor. It attaches through your shotgun's choke threads using an Echo adapter, which replaces your factory choke and provides an external locking ring the suppressor mounts to. Every Salvo setup needs an Echo adapter matched to the barrel's choke pattern.
Can I shoot steel shot through this Full choke adapter?
No, SilencerCo advises against running steel shot through Full or Improved Modified constrictions. Steel doesn't compress like lead and can damage a tight choke. If steel loads are part of your plans, look at the Improved Cylinder version of the Echo adapter, and stick with lead or other soft shot through this Full model.
Does the Echo adapter change my shot pattern compared to a regular Full choke?
The adapter carries a true Full constriction, so your patterns should behave like a standard extended Full choke. That's the whole point of the Echo system: you keep your preferred spread while gaining a suppressor mount. One caveat is that the Salvo system isn't compatible with flight-controlled wads, so pick shells with standard wads for best results.
