The Ouch Mouse is a compact, precision-engineered 5.7 suppressor built for shooters who want maximum performance in the smallest possible package. Machined from ultra-durable 17-4 stainless steel, this 5-inch, 7.1 oz suppressor delivers exceptional sound reduction while staying light, maneuverable, and perfectly balanced on small-caliber rifles. Designed specifically around 5.7x28 and .223/5.56 bolt-action platforms, the Ouch Mouse offers a sleek 1.2345" outside diameter, making it ideal for varmint hunting rigs, lightweight precision rifles, and compact bolt-gun builds. Its internal geometry reduces muzzle blast without adding unnecessary length or weight to the setup.
