The Dark Mountain Arms Stow Away 5.7x28mm is a purpose-built takedown rifle engineered for hunters, backcountry shooters, and overlanders who refuse to compromise on capability for the sake of pack weight. Unlike conventional rifles, the Stow Away breaks down to half its firing length—small enough to stow in most backpacks—yet reassembles in seconds to full operational readiness. Its bolt-action design and detachable barrel system make it ideal for anyone running ultralight basecamp loads or needing a reliable backup firearm that doesn't demand dedicated transport.
Built on an aluminum and steel frame with corrosion-resistant finish, this 2.8-pound rifle handles the weight-conscious reality of extended trips. The 16-inch threaded barrel (1/2"x28) opens options for suppressor-ready setups, while the Picatinny rail gives you flexibility in optics mounting. A half-cock safety position adds an extra margin of security during handling and transport. The 5.7x28mm cartridge delivers modest recoil and energy signature—practical for small game and varmint work at reasonable distances.
Dark Mountain Arms, a veteran-owned manufacturer, engineered this rifle with caliber flexibility in mind: swapping to a different cartridge requires only a barrel and bolt face change, making the platform adaptable to evolving needs without a full rifle purchase. Whether you're scouting remote terrain, running minimalist overlanding setups, or keeping a capable takedown rifle as emergency backup, the Stow Away delivers genuine utility in a package that won't anchor your pack.
| Caliber | 5.7x28mm |
| Action | Bolt-action, single-shot |
| Barrel Length | 16 inches |
| Barrel Threading | 1/2"x28 |
| Length (Barrel Attached) | 31.78 inches |
| Length (Barrel Detached) | 16.65 inches |
| Height | 6.88 inches |
| Thickness | Less than 2 inches |
| Weight | 2.8 pounds |
| Materials | Aluminum, steel, glass-filled nylon |
| Finish | Corrosion-resistant |
| Safety | Single action with half-cock position |
| Rail System | Picatinny rail (optics-ready) |
Yes. When the barrel is detached, the rifle measures under 17 inches in length, making it compact enough to pack into most full-size backpacks without external attachment. This is the core design advantage for backcountry hunters and overlanders.
The 16-inch barrel is threaded 1/2"x28, which is the standard suppressor thread pitch. You can mount any suppressor with a 1/2"x28 male connection, though you'll need to verify suppressor legality in your state and comply with all federal NFA regulations.
Changing calibers requires only a barrel swap and a bolt face change—no gunsmith visit needed. This modular approach lets you adapt the rifle to different game or mission sets without purchasing an entirely new firearm.
The rifle features a Picatinny rail for mounting optics. You'll need to source your own scope, red dot, or other sight—the rail is already integrated and ready to accept standard Picatinny-mount optics.
