SilencerCo AC1315 Echo Choke Adapter 12 Gauge Improved Modified Browning Invector Plus

The SilencerCo AC1315 Echo Choke Adapter is a purpose-built choke tube that lets a shooter mount the Salvo 12 shotgun suppressor to a 12-gauge shotgun. It is cut to Improved Modified constriction and threaded in the Browning Invector Plus pattern, so it drops directly into the muzzle of any compatible 12-gauge in place of the gun's existing choke.

Because every shotgun brand uses a different choke-thread standard, SilencerCo offers the Echo choke adapter line as a set of single-pattern options. The AC1315 is the dedicated Browning Invector Plus variant in Improved Modified constriction, finished in a low-glare black to blend with the host shotgun's muzzle. Once threaded in, the choke provides the mounting interface the Salvo 12 threads onto, eliminating the need for clamps or adapters at the muzzle.

Select the choke style that matches your shotgun's thread spec and the spread pattern you want to preserve. The AC1315 is sold as a single Echo Choke Adapter only; the Salvo 12 suppressor and shotgun are not included.
