Yes, these are AI mockups. Congratulations on spotting it before racing to the comments.

They’re mockups because we’re not ordering 500 hoodies and hats just to find out you guys only wanted gun parts.

But we’ve had enough requests for MechTech gear that we’re seriously considering it. Hoodies, hats, tees and maybe a few other things. And if there’s enough demand, the real stuff could look a whole lot like what you’re seeing here.

So before we start making stuff:

Would you genuinely buy MechTech gear?

Any Mechtech can ship to your door in every state, except California. The Mechtech is a federally un-controlled product as it is not a fi***rm.

Every user needs to be aware of their local laws before assembling this into a fi***rm. Not all configurations of our CCU may be legal in all areas.

Mom said I could bring three things.

Tired of losing your telephone, pocket change, and other valuables into that troublesome space between your seat and console?

Simply insert one MechTech Carbine Conversion Unit and PRESTO! That pesky gap is occupied!

Modern solutions for the modern motorist.

The MechTech CCU turns your compatible pistol frame into a seriously compact carbine, and it ships directly to your door. No FFL required.

Big capability. Very little real estate.

Truck gun, but make it modular. ↔️🔫

Happy Labor Day weekend. We’ll be conducting important research. 🇺🇸🧪🫡

Still skeptical? Perfect. Hickok45 already did your homework.

In this review, he’s using a G***k 17 + MechTech CCU, and spends the duration of the video casually nailing everything he points it at while addressing the questions we get all the time about legality, reliability, how it works, and whether it’s actually any fun to shoot.

And while this one’s mounted on a G***k 17, there are more than 20 compatible pistol models and variants across G***k, PSA Dagger, Springfield XD/XD(M), and 1911 platforms.

If you’ve got questions about the CCU (or have been cautious because of all the keyboard warriors in our comment sections 😂) this one is well worth watching.

MechTech CCU in 10mm on a Springfield XD-M, factory Re*****on 10mm ammo, and a target sitting almost 500m out.

US Optics LR-17 up top, ZRODelta return-to-zero mount holding it down. Built in Kalispell, Montana.

Our CCU’s makes “effective range” more of a suggestion.

Compact when you want it. Carbine when you need it.
