Description
The SilencerCo AC1347 Echo Choke Adapter is a dedicated choke mount adapter engineered specifically for the Kel-Tec KSG bullpup shotgun. Machined in an Improved Cylinder choke constriction with a durable black finish, this adapter threads onto the KSG’s factory barrel threads and allows the shooter to attach a SilencerCo Salvo 12 suppressor while still running a true, full-size choke for consistent shot pattern and reliable feeding.
Unlike a standard choke tube, the AC1347 is part of the Echo thread-adapter family from SilencerCo and is purpose-built for the KSG platform only, giving KSG owners a clean, factory-engineered mounting solution for the Salvo 12 rather than improvised spacers or third-party workarounds. Its Improved Cylinder geometry delivers an open, versatile pattern suitable for buckshot, slugs, and general-purpose defensive or duty use, and the adapter installs just like a conventional choke for fast setup and removal.
Whether you are running a 12 Gauge KSG for home defense, patrol, or range work and want to add the Salvo 12 suppressor to your setup, the AC1347 provides the missing link between the KSG barrel and your suppressor. Use it as designed: threaded onto the KSG barrel, with the Salvo 12 mounted in place per SilencerCo’s instructions, and you retain full choke function while gaining the sound suppression of the Salvo 12.
