The Q Erector .22 LR modular suppressor is a configurable rimfire can from Q (brand part no. SIL-ER-22). At full length it measures 7.6 inches, and its modular design lets you run it shorter when a compact host calls for less length. That flexibility lets one suppressor move between rimfire rifles and pistols. For a .22 shooter who wants a single can for several guns, the Erector covers the range.
