Description
Just Right Carbines built the Spark Takedown around a pretty simple idea: what if you could have a full-size 9mm carbine that disappears into a bag when you need it to? The SPARK TD delivers on that with a twist-off takedown tube forend that separates the barrel from the receiver without tools in a matter of seconds. Reassembly is just as quick. Whether you're heading into the backcountry, throwing it behind the seat of a truck, or just want something easy to store and transport to the range, the form factor alone makes it stand out.
The 17" threaded barrel is parkerized 4140 chromoly steel with a 1:16 twist and is threaded 1/2×28 TPI at the muzzle, so it plays well with a wide range of suppressors and muzzle devices right out of the box. The receiver, trigger housing, and mag well are machined from aerospace-grade 6061-T6 aluminum, keeping weight down while maintaining solid durability. The blowback-operated action runs on standard AR-15 fire control components, which makes parts and trigger upgrades easy to source and affordable.
One of the more practical features on the SPARK is the interchangeable magazine well system. It ships configured for double-stack Glock-pattern mags, but the well can be swapped to accept S&W M&P, Citadel CP, or FMK magazines. If you're already running a Glock 9mm, your magazines work directly in the carbine, which is a genuinely useful setup for a truck gun, camp gun, or backup kit. The charging handle and ejection port are both configurable for left- or right-handed use, so it's a legitimate option for lefties without any aftermarket work needed.
The 6-position collapsible stock rides on a commercial-spec M4 buffer tube and accepts standard AR-15 furniture if you want to make it your own. The flat-top receiver gives you a standard Picatinny rail for mounting an optic or red dot. Keep in mind the action does not hold open on the last round, which is worth knowing going in. Overall, the SPARK Takedown is a well-thought-out platform for anyone who wants a capable, packable 9mm carbine that shares ammo and magazines with a carry pistol.

Frequently Asked Questions
Does the JRC Spark Takedown require any tools to break down?
No tools needed at all. The takedown tube forend unscrews with a simple twist, and once it's off the barrel pulls free from the receiver. The whole process takes just a few seconds, and putting it back together is equally straightforward. It's genuinely one of the faster takedown designs in the PCC category.
What magazines does the JRC Spark Takedown PCC work with?
It ships configured to run double-stack Glock-pattern 9mm magazines, which includes standard Glock factory mags as well as most compatible aftermarket options. The magazine well is also interchangeable, so you can swap it to accept S&W M&P, Citadel CP, or FMK magazines if that's what you're already running. This makes it a practical companion to a wide range of 9mm carry pistols.
Is the barrel threaded for a suppressor?
Yes, the 17" barrel is threaded 1/2×28 TPI, which is the standard thread pitch for 9mm suppressors and muzzle devices in the US. It's a common size, so you'll have plenty of options whether you're running a can or just want to add a muzzle brake or compensator.
Can left-handed shooters use the JRC Spark Takedown comfortably?
The SPARK Takedown is designed with ambidextrous operation in mind. Both the charging handle and the ejection port can be configured for either left- or right-handed use, so lefties don't have to settle for a right-hand-only setup. The safety and magazine release are standard AR-style, and aftermarket ambidextrous AR safeties can be swapped in if needed.
Does the JRC Spark Takedown hold the bolt open on the last round?
No, the action does not automatically lock back on an empty magazine. When you run dry, you'll need to drop the mag, insert a fresh one, and manually cycle the charging handle. It can be locked back manually to verify clear, but there's no automatic last-round bolt hold-open, so it's worth keeping round count in mind during use.
What kind of customization options does the Spark Takedown support?
Quite a bit, actually. The flat-top receiver has a standard Picatinny rail for optics, lights, or other accessories. The stock mounts on a commercial-spec M4 buffer tube, which means standard AR-15 stocks drop right on. The fire control group uses AR-15 standard components, so trigger upgrades are easy and affordable to source. The forend can also be swapped for an M-LOK version if you want more accessory mounting real estate.
