Description
The Kel-Tec KSG is one of the more unique shotguns out there, and if you own one alongside a Salvo 12, this little adapter is the missing link between the two. The SilencerCo Echo choke adapter (AC1347) threads onto the KSG's barrel and gives you the external mounting interface the Salvo 12 needs to lock up tight. It is one of those parts that does exactly one job, and it does it right.
How the Echo KSG Adapter Works
Unlike the Echo adapters SilencerCo makes for Remington, Mossberg, and Benelli pattern shotguns, the KSG version is an external adapter rather than a replacement choke tube. That means it mounts to the outside of the barrel and does not change your spread pattern, so you keep the choke performance you are used to while gaining a secure attachment point for the suppressor. The Salvo 12 spins on and locks up with no wobble, which matters a lot when you are hanging a full-size shotgun can off the end of a bullpup.
Built for the KSG, Nothing Else
Worth repeating: this mount is dedicated to the Kel-Tec KSG. SilencerCo makes separate Echo adapters for Saiga and Vepr shotguns and choke-style versions for most common 12 gauge platforms, so make sure you grab the right one for your gun. The matte black finish blends right in with the KSG's factory look, and at just a couple ounces of shipping weight, it adds next to nothing to the front of the gun on its own.
Why KSG Owners Grab This Adapter
A suppressed KSG is a genuinely fun setup. The bullpup layout keeps the overall package short even with the Salvo 12 attached, and taming that 12 gauge blast makes range sessions a whole lot more pleasant for you and everyone standing next to you. If the Salvo 12 is already in your safe or on your wish list, this adapter is the piece that ties the whole setup together.

Frequently Asked Questions
Will the Echo KSG choke adapter fit shotguns other than the Kel-Tec KSG?
No, this specific adapter is made only for the Kel-Tec KSG. SilencerCo builds a separate Echo adapter for Saiga and Vepr shotguns and choke-style versions for platforms like Remington, Mossberg, Benelli, and Browning. Double check that you are ordering the version that matches your shotgun before you buy.
Does the SilencerCo Echo KSG adapter change my shot pattern?
It does not. The KSG version is an external adapter rather than a replacement choke, so it mounts to the barrel without altering your spread. That is a nice perk since you keep the patterning you already know while gaining the Salvo 12 mounting interface.
What suppressor does this adapter work with?
This adapter is purpose-built for the SilencerCo Salvo 12 shotgun suppressor. The Salvo 12 attaches to the adapter's external threads and locks up securely on the KSG. It is not designed as a universal mount for other shotgun suppressors.
Is the Echo choke adapter hard to install on a KSG?
Not at all. It threads onto the KSG's barrel, and once it is snugged down the Salvo 12 attaches and detaches quickly whenever you want to run suppressed. Anyone comfortable with basic gun maintenance can handle it, though it is always smart to follow SilencerCo's instructions for proper torque and alignment.
