The modular Osprey Micro is rimfire, full auto rated suppressor that shares design similarities with the popular full size Osprey line. It has a flat sight plane for easy target acquisition and can be reduced from 4.6a ^2 to 3.1a ^2 in length easily with provided tools. Durable enough to be used with a variety of rimfire calibers and ammunition, the Osprey Micro remains easy to clean after hundreds of rounds fired. Mfg: Silencerco
