Caleb (Brownells):
Hi, Caleb with Brownells here, back again with Adam from Spiritus Systems. In today’s Product Spotlight, we’re taking a look at the JSTA Pouch.
Adam (Spiritus Systems):
Thanks for having me again. The JSTA Pouch was originally developed as a belt-mounted solution for guys who wanted to carry a fast mag on their belt, but also have some general-purpose storage. Over time, we evolved it to also be MOLLE-compatible based on field feedback. People wanted to mount it on their plate carrier cummerbunds or chest rigs too.
As for the design, it’s a flapped pouch. We use a piece of Squadron material that stays free from the Velcro so you can easily index and open it. For size reference, we’ve stuffed a smoke grenade prop inside—it gives you an idea of interior space.
Inside, it’s a Velcro-lined open pouch. You can add inserts if you want, and there’s also a stash pocket in the back for organization—great for markers, chemlights, etc. We used a Velcro flap for quick access, ideal for assaulters where noise isn’t a major concern.
Caleb:
Right, so functionality was really prioritized here.
Adam:
Exactly. The rear pouch is Velcro-lined and accepts our inserts—most commonly a single rifle and a single pistol magazine. You can run just a single 5.56 or 7.62 mag too. These inserts are retained by elastic and easy to access. Typically, guys will reload from their plate carrier, then restock this pouch.
You can also run a belt through the back pass-through for use with a standard pants belt. That’s a great intro use case—especially if you’re just getting into carbine shooting. Say you just bought a Brownells Knights Armament rifle but don’t have a chest rig or plate carrier—this pouch gives you a flexible way to carry a couple of mags and some range gear.
It’s perfect for early training—you don’t need to walk back to a bench or stuff mags in your pockets. Just belt it on and go.
Caleb:
Very versatile.
Adam:
Yeah. You can also MOLLE it to a belt. On my personal belt, I MOLLE it on so it doesn’t shift. I run a double-stack 9mm Staccato pistol mag and a standard 5.56 rifle mag. Inside the pouch, I carry a Blue Force Gear MARCO chemlight pack and extra Sharpies—always losing those at the range!
I usually leave the rest of the pouch empty so the flap can cinch down tightly and stay low profile. But if I need to stash gloves or a mag after a tac reload, it works great as a mini dump pouch too.
Caleb:
Makes perfect sense. It’s a practical, flexible product I think a lot of our viewers will find really useful—whether at the range or out in the field.
Adam:
Absolutely.
Caleb:
Adam, thanks again for coming out and giving us the rundown.
