Nominally 1” in diameter and 2.8” in length, weighing in at a mere 2.6 ounces with a black cerakote finish. The Bowers BITTY is rated for .17 rimfires, .17WSM, .22, .22 Mag, .22 Hornet, FN 5.7×28 and rated for full auto in .22. The BITTY on a .22 rifle performs akin to many other manufacturer’s full sized .22 suppressors. On a pistol it is small, fun and comfortable to shoot coming in well under the threshold for hearing safe. It is also hearing safe on a .22 Mag rifle. Our testing was performed with CCI standard velocity .22 ammunition.
