SilencerCo Charlie Front Cap – .223/5.56

The SilencerCo Charlie front cap (brand part no. AC4736) is a modular suppressor accessory rated for .223 Rem/5.56 NATO, designed to switch calibers on compatible SilencerCo suppressor bodies without buying a second complete suppressor. It’s also compatible with MAAD brake systems, giving owners flexibility in how they configure their host suppressor for different calibers or muzzle devices. This is a replacement or upgrade part for a suppressor a customer already legally owns and has transferred through NFA channels; it is not itself a regulated firearm component. Shooters running multiple calibers through the same SilencerCo platform rely on caps like this to avoid owning a dedicated can for every chambering.
