The GSL Tomcat 22 LR suppressor is a full-auto rated rimfire can that gives a .22 shooter the look and feel of a suppressed AR at the cost of .22 LR practice (GSL part no. TC-100-SUP). It weighs 6.25 ounces, measures 6.5 inches long and 1.375 inches across, and GSL rates it at 40 dB of reduction. The body is aluminum with a hard coat anodized finish, and it mounts through GSL’s Bi-lock quick-detach system with a 1/2×28 Bi-lock mount in the package. It is built for rimfire AR trainers and plinkers who want a full-size profile without full-size weight.
