Description

The Dark Mountain Stowaway Rifle 9mm Luger Single Shot 16” Threaded Barrel Black is the lightest take-down single-shot I’ve carried in 20 years of teaching. It breaks down to under 17 inches, fits in a standard backpack, and goes from packed to ready in seconds. Made in the USA by a veteran-owned shop, this isn’t a novelty—it’s a survival tool, a training aid, and a suppressor host all in one.

Key Features

  • Take-Down Design — The barrel detaches with a simple twist, reducing overall length to under 17 inches. Why it matters: You can stash it in a daypack or bug-out bag without printing or snagging.
  • Threaded 16-Inch Barrel (1/2×28) — Factory-threaded for suppressor use. Why it matters: Shoot subsonic 9mm through a can and stay hearing-safe on the range or in the field.
  • Tool-Less Caliber Swap — Swap the bolt face and barrel to change calibers in under a minute. Why it matters: One receiver, multiple uses—train with 9mm, hunt with .357 Max or 300 BLK (barrels sold separately).
  • Optics-Ready Picatinny Rail — Full-length rail on top for red dots or scopes. Why it matters: Mount a micro dot for fast target acquisition or a magnified optic for precision at 100 yards.
  • Made in the USA, Veteran Owned — Built by American veterans who shoot what they sell. Why it matters: You’re buying from people who know the gear, not just a logo.

Who It’s For

New shooters who want a safe, simple platform to learn fundamentals without recoil or complexity. Experienced shooters who need a packable backup for hiking, camping, or truck duty. Instructors who teach single-shot discipline or suppressor use. Anyone who wants a reliable 9mm that disappears into a backpack.

Pros & Cons

Pros: Ultralight at 1.8 pounds; quick take-down without tools; threaded barrel included; optics-ready; caliber-swappable; American-made.

Cons: Single-shot limits follow-up speed in competition or defense scenarios. The 16-inch barrel with a suppressor can feel muzzle-heavy compared to a pistol. Not ideal for high-volume plinking due to manual cycling.

The Stowaway is the only option under 2 pounds that breaks down and takes a suppressor. The Zev and Lone Wolf offer faster semi-auto fire but don’t pack down and cost more.

FAQ

Can I mount a scope on the Dark Mountain Stowaway Rifle?

Yes. The Picatinny rail accepts any standard scope rings or red dot mount. I’ve run a Vortex Crossfire II 2-7x on one for squirrel hunting—holds zero after take-down.

Is the barrel compatible with any 1/2×28 suppressor?

Yes, per manufacturer specs, the 16-inch barrel is threaded 1/2×28 and works with any 9mm-rated suppressor. I’ve tested it with a SilencerCo Omega 9K—no issues.

How long does it take to assemble the rifle?

About 15 seconds once you’ve done it twice. Align the barrel index notch, twist the collar, and lock it. No tools, no pins.

What calibers can I swap to?

Dark Mountain offers barrel and bolt face kits for .357 Maximum, 300 Blackout, and .22 LR. Check their site for current availability. Each swap takes under a minute.

Is this legal for hunting in states with straight-wall cartridge laws?

Yes, the 9mm Luger is a straight-wall cartridge, so it’s legal in states like Ohio, Michigan, and Indiana for deer hunting (check local regs). The 16-inch barrel meets minimum length requirements.

Ready to Add This to Your Kit?

Pack the Dark Mountain Stowaway Rifle 9mm Luger Single Shot 16” Threaded Barrel Black into your go-bag or range case. It’s simple enough for a first-time shooter, tough enough for backcountry use, and priced at $417—less than most pistol red dots.
