The Anechoic PipSqueak 22 rimfire suppressor in flat dark earth (Anechoic part no. PSQ-FDE) is a compact can that weighs only 1.5 ounces. Anechoic calls it the shortened version of its AnechoX 22, and it threads onto a rimfire rifle or pistol with a fixed 1/2×28 thread. It is quiet on .22 LR, .22 Mag and .17 HMR, and it is not rated for any .223/5.56. The tan finish suits an FDE rifle or a desert-colored rimfire build. It is an easy add for a small-game rifle, a trail pistol or a range trainer.
