Description
You know that feeling when you see a classic silhouette but it’s chambered in something a little more… practical for the local range? That’s the first thought I had when I got my hands on the Arsenal Firearms SLR-106UR 8.5″ Krink Pistol 5.56×45 NATO/223. It’s a compact, AK-pattern pistol that takes the iconic ‘Krinkov’ short-barreled aesthetic and mates it with the ubiquitous 5.56 NATO round. This isn’t a museum piece; it’s a modern, highly portable firearm built on a milled receiver for serious durability, and it’s priced at a very compelling $751.99. Let’s talk about what that actually means on the range and in the safe.
Here’s the thing—the SLR-106UR isn’t just a shortened AK. It’s a specific adaptation of the Bulgarian AR-M9 design, and that pedigree shows. The heart of it is that milled receiver. Compared to a stamped variant, it adds a noticeable heft and a rock-solid feel that translates directly to perceived longevity. I’ve put a few hundred rounds of mixed .223 and 5.56 through this one, and the action just gets smoother. The 8.5-inch chrome-lined barrel is the star for compactness, but remember, with that length you’re trading some velocity for extreme maneuverability. It’s a trade-off that makes perfect sense for a vehicle or backpack gun, or simply for a supremely handy range toy that draws looks and questions.
Out of the box, it’s a straightforward, no-frills firearm. The controls are pure, familiar AK: a robust safety lever, a bolt hold-open device, and a paddle-style magazine release. It comes with a single 30-round Circle 10 polymer magazine, which is the gold standard for 5.56 AK platforms. The pistol grip is a basic black polymer, and the forend is a classic AKM-style wood laminate that looks great but can get warm. The good news? The platform is famously customizable. That forend can be swapped for modern rails from companies like SLR Rifleworks or TDI, and the rear trunnion is set up for a side-folding brace or stock adapter, should you choose to go that route. The rifle weighs in at a dense 6.5 pounds, which helps manage the inherently snappy recoil impulse of a short-barreled 5.56.

Pros & Cons
The pros are compelling: you get an incredibly tough, compact platform with legendary AK reliability in a common caliber. The milled construction is top-tier, and the classic Krink look is undeniable. It’s also drop-in ready for a vast aftermarket of AK accessories. The cons? That short barrel means significant fireball and blast—wear your ear pro. It’s also a niche firearm; magazines are more specific (true 5.56 AK mags like Circle 10s or WBP) than AR-pattern ones, and holsters? Forget it. This is a sling or case gun. And at 6.5 pounds, it’s not light for its size.
Who is this for?
This pistol is for the AK enthusiast who wants a compact, high-quality build without venturing into obscure calibers. It’s for someone who appreciates the milled-receiver pedigree and intends to use it as a base for a personalized SBR or braced pistol. It’s also just a plain fun range gun for the collector who wants something different from the sea of AR pistols. Given its compact 19.5-inch overall length, it stows away easily. This unit is available at firearms-missouri.com for Missouri residents and nationwide, with an FFL transfer required for firearm purchases.
Frequently Asked Questions
Q: Will this take standard AR-15 magazines?
A: No. The SLR-106UR is designed for specific 5.56x45mm AK-pattern magazines. Your best bets are Bulgarian Circle 10 magazines, Polish WBP, or other dedicated 5.56 AK mags. Standard AR mags will not fit or function.
Q: Is the barrel threaded?
A: Yes, the 8.5-inch barrel features standard 14x1mm LH threads, which is common for AK platforms. This allows for the attachment of muzzle devices like brakes or flash hiders. Just be mindful of overall length and legalities if adding a permanent device.
Q: Can I put a stock on this?
A: As it is sold, this is a pistol. Attaching a stock to it would create a Short-Barreled Rifle (SBR), which is regulated under the NFA and requires prior approval via a Form 1, tax stamp, and engraving. You can, however, legally attach a pistol brace to the rear trunnion without NFA paperwork, provided you follow current ATF guidelines.
