The Archangel 10/22 Faux Suppressor is designed to fit on a standard-profile Ruger 10/22 barrel. Requiring only the removal of the front-sight post from the OEM barrel, the black polymer Faux Suppressor slips into place, and is secured by a small pin (included) that engages the OEM dove-tail. The Archangel suppressor is fully compliant with State and Federal laws, and is an upgrade to your firearm providing the ultimate SpecOps look.
