The Otter Creek Labs Titanium .22 LR direct-thread suppressor in FDE (Otter Creek Labs part no. TUM22FDE) is a light, compact rimfire can that mounts straight to a half-inch by 28 threaded barrel. Otter Creek Labs makes it from 100 percent titanium, so it weighs only 4 ounces while measuring 5.18 inches long. The company describes it as affordable, small and quiet, with little to no first-round pop depending on host and ammunition. It is easy to take apart, clean and put back together, which matters for a rimfire suppressor that sees a lot of dirty ammunition. It backs the build with a lifetime warranty.
