Description
You’re looking for a compact, hard-hitting AK platform that doesn’t break the bank, but the options seem to be either cheap kits with questionable quality or boutique builds with four-figure price tags. Where’s the middle ground? The Blackheart M92 AK Short Barrel Rifle, 7.62x39mm, 10″, Side Folder, ALL NFA RULES APPLY aims to be exactly that: a purpose-built, no-fuss SBR that delivers serious capability for the money.
The Blackheart M92 is a factory-configured, 10-inch barreled AK pistol variant designed to be registered as a Short Barrel Rifle (SBR) under the NFA. It chambers the potent 7.62x39mm round, features a robust side-folding stock for compact storage and transport, and is sold as a complete, ready-to-file firearm for $1612.18. This isn’t a parts kit project; it’s a turnkey solution for the shooter who wants a compact AK’s performance without the assembly headaches. It ships to Missouri and compliant US states.
Let’s talk value. Building a similar SBR from a parts kit often means sourcing a receiver, barrel, and compliance parts, then paying for professional assembly. By the time you add a quality side-folding stock mechanism and the tax stamp, you’re often looking at a similar or higher total cost. The Blackheart M92 comes to you as a complete, coherent package. The 10-inch barrel is the sweet spot for the 7.62×39 cartridge, retaining formidable ballistic performance while drastically reducing overall length compared to a 16-inch rifle. The side-folding stock is a huge practical advantage—it makes the gun easy to stow in a vehicle or pack without sacrificing a solid cheek weld and shoulder point when you need it. Here’s the thing—this setup is drop-in ready for optics if you choose, with many users successfully mounting red dots via aftermarket rails that attach to the rear sight base or side rail.
The build uses a combination of new, US-made components and quality imported parts to hit its price point. It’s designed to work with standard AKM-pattern magazines, so your existing stack of Bulgarian steel, Croatian BHO, or Magpul PMAGs will run without issue. The side folder itself is a solid, battle-proven design, locking up tight in both extended and folded positions. At just over 6.5 pounds unloaded, it’s manageable for its size, and the shorter barrel shifts the balance point rearward for faster handling. The total length with the stock folded is a mere 20-22 inches, making it incredibly portable.

Pros: The primary advantage is cost-effectiveness for a complete SBR platform. You get a functional, compact rifle without custom gunsmithing bills. The 7.62x39mm round remains affordable for practice and effective for defense. The folding stock is a major utility upgrade over a pistol brace, providing real stability. Its compatibility with ubiquitous AK magazines and many standard AKM accessories keeps long-term costs down.
Cons: The obvious one is the NFA process—this requires a $200 tax stamp, fingerprints, photos, and a wait. It’s not a grab-and-go purchase. The short barrel increases muzzle blast and flash, making a muzzle device or suppressor highly recommended. As with many value-focused firearms, the finish may be utilitarian, and you might want to upgrade the furniture or sights to personal taste.
So who is this for? It’s ideal for the Missouri shooter who already understands the NFA process and wants a compact, truck-ready rifle that packs a serious punch without a custom-shop price tag. It’s also a smart pick for the AK enthusiast looking for a dedicated SBR host that’s more refined than a DIY build but less expensive than a high-end import. Think of it as a practical working gun, not a safe queen.
Frequently Asked Questions
Q: Does this come as a pistol or a rifle, and what’s required to take possession?
A: It is transferred as a “Firearm” subject to NFA rules (specifically, as a Short Barrel Rifle). You must complete an ATF Form 4 through your dealer, pay the $200 tax, and receive approval before taking possession. An FFL transfer required for firearm purchases is just the first step in a longer process.
Q: What muzzle device is installed, and is the barrel threaded?
A: The barrel is typically threaded 14x1mm LH, and it commonly comes with a simple slant brake or birdcage-style device. This standard threading allows you to easily install a wide range of AK-pattern muzzle brakes, compensators, or suppressors with the appropriate adapter.
Q: Can I use standard AK-47 furniture and parts on this?
A: Mostly, yes. The receiver and front end are based on the Yugoslavian M92 pattern, which is largely AKM-spec. Standard pistol grips and some lower handguards will fit. However, due to the shorter gas system and barrel profile, the gas tube and upper handguard are specific to the M92. Always verify part compatibility for this specific model.
If a compact, potent AK SBR that focuses on performance over polish fits your needs and budget, the Blackheart M92 represents a straightforward path to ownership. You can find full details and availability at firearms-missouri.com for Missouri residents and nationwide.
