Dark Mountain Arms Stowaway Single-Shot Pistol – 5.7×28 | 5″ Threaded Barrel | Brace Adapter Ready

The Dark Mountain Arms Stowaway is a large-format, bolt-action single-shot pistol engineered for maximum versatility and portability. Chambered in the flat-shooting 5.7×28 cartridge, this innovative handgun features a removable 5-inch barrel with a 1/2×28 threaded muzzle, making it suppressor-ready right out of the box. The barrel removal system dramatically reduces overall length for easy storage and transport, while also enabling straightforward caliber conversions with a simple bolt face and barrel swap.

The Stowaway comes equipped with a 1913-style Picatinny rail adapter for attaching a folding brace (all NFA laws apply) and an integrated optics-ready Picatinny rail for your preferred red dot or magnified optic. Built in the USA by a veteran-owned and operated company, Dark Mountain Arms delivers rugged construction and American craftsmanship in a compact, adaptable platform.

Whether you’re looking for a backcountry sidearm, a suppressor host, or a modular single-shot pistol with multi-caliber capability, the Stowaway is purpose-built to deliver. Order online today at VanTon Arms and enjoy competitive pricing with fast nationwide shipping.
