The Anechoic PipSqueak 22 rimfire suppressor in olive drab (Anechoic part no. PSQ-OD) is a pocket-sized can at just 1.5 ounces and 3.5 inches long. It is the shortened version of Anechoic’s AnechoX 22, with a fixed 1/2×28 thread that fits almost every threaded rimfire. Anechoic rates it for .22 LR, .22 Mag and .17 HMR, and it is not rated for any .223/5.56. The olive drab finish suits hunting rifles and woods guns. It is a simple, light can for squirrel rifles, trail pistols and backyard plinkers.
