Description
It’s a 9mm takedown carbine built for durability and modularity. The Just Right Carbines Gen3 Takedown Marine 9mm 17″ Threaded Stainless Steel Barrel Electro-Less Nickel Finish Adjustable Quick Release Stock Black 17rd Glock Compatible Magazine is a purpose-built pistol-caliber carbine (PCC) designed for easy transport, corrosion resistance, and compatibility with the most popular handgun magazine system in the world. I’ve run a few hundred rounds of mixed brass and steel case through one, and the takedown feature is the real star—it makes storage and cleaning a breeze.
Key Features
- True Takedown Design: Breaks down into two compact halves without tools for discreet transport or storage.

Weighing in at about six and a half pounds, it has a solid, balanced feel that soaks up 9mm recoil. The real beauty is in the details—the stock adjusts with a simple pull and twist, and the whole system is drop-in ready for anyone familiar with an AR platform. The takedown mechanism itself is robust; you get a positive lock-up every time you reassemble it, with no wiggle or play. At $675.57, it sits in a competitive spot for a feature-rich, corrosion-resistant PCC.
Who This Carbine Is For
This is for the shooter who values practical utility over pure tacticool. It’s a fantastic truck or boat gun for Missouri landowners, thanks to that nickel finish. It’s a brilliant choice for a home defense carbine where magazine commonality with your Glock 17 or 19 matters. It’s also an ideal trainer or introductory rifle—the 9mm recoil is minimal, ammo is (relatively) affordable, and the manual of arms is straightforward. Look, if you need a compact, reliable, and weather-resistant carbine that shares mags with your sidearm, this checks every box.
Pros & Cons
Pros: The takedown function is genuinely useful and well-executed. Corrosion resistance is top-tier for humid Missouri summers. Glock magazine compatibility is a huge logistical and cost advantage. The adjustable stock makes it easy to fit different shooters. The threaded barrel is a nice value-add right out of the gate.
Cons: It’s not a lightweight AR-9. Some pure AR purists might prefer a more traditional buffer tube setup. The nickel finish is excellent but can show smudges. You’ll likely want to invest in more magazines, but that’s easy since they’re standard Glock mags.
Frequently Asked Questions
Q: What Glock magazines does it use?
A: It’s compatible with standard Glock 17 (9mm, 17rd) and Glock 19 (9mm, 15rd) magazines, including Gen 3, 4, and 5 models. It ships with one 17-round magazine.
Q: Is the barrel threaded for a suppressor?
A: Yes, the 17-inch stainless barrel has 1/2″-28 threads, which is the standard for many 9mm muzzle devices and suppressors. Always check thread alignment with a gage before mounting.
Q: How difficult is the takedown process?
A: It’s incredibly simple. Push a takedown pin, separate the upper and lower, then unscrew the barrel collar by hand. The whole process takes about 10 seconds with no tools required, making it perfect for secure storage in a compact case.
This carbine delivers a specific set of features that are hard to find elsewhere at this price.
