Ouch Mouse – Compact 5.7 Suppressor Made From 17-4 Stainless Steel
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.
The Ouch Mouse uses the industry-standard Alpha thread pattern and includes a 1/2x28 direct-thread mount, making it compatible with most 5.7 and 5.56 bolt-gun barrels right out of the box.
