The Q Erector .22 LR modular suppressor is a rimfire silencer you build to length by adding or removing sections, from 1.9 to 7.6 inches (Q part no. SIL-ER-22). This clear anodize version uses a tubeless aluminum and stainless steel design, and Q says fully assembled it weighs less than a standard QD sling swivel and cup. It direct mounts and comes apart easily for cleaning, which counts on a dirty-burning rimfire. Q positions it for pistols and rifles alike, so one can can move between several .22 guns.
