The Archangel 10/22 fauz suppressor is designed to fit on a standard-profile Ruger 10/22 barrel. The black polymer faux suppressor slips into place and is secured by a small pin (supplied) that engages the OEM dove tail. It is fully compliant with State and Federal laws. It is also a cosmetic accessory that creates the ultimate Spec-Ops look, requiring only the removal of the front-sight post from the OEM barrel. Made in the USA.
