Arsenal SLR-106UR 5.56 NATO AK-74-Pattern Semi-Automatic Pistol – Cold Hammer Forged 8.5” Chrome-Lined Barrel, Bulgarian Import
This Bulgarian-made Arsenal SLR-106UR pistol combines the compact “Krinkov” profile with 5.56 × 45 mm NATO chambering, a rare pairing that has seen only limited U.S. importation. Built on a stamped AK-pattern receiver with a factory side-folding hinge block (no stock installed), it features a cold hammer forged, chrome-lined 8.5-inch barrel threaded 24 × 1.5 mm RH and capped with a multi-baffle muzzle brake. Collectors value its Circle 10 polymer magazines, chrome-lined bore, and left-side optics rail, all packed into a durable, black-finished package.

The SLR-106UR pistol is built on Arsenal’s proven long-stroke gas piston system, delivering AK-reliable cycling in a compact 8.5-inch-barreled package. The barrel is both cold hammer forged and chrome lined, maximizing service life and corrosion resistance even under heavy firing schedules.
A 24 × 1.5 mm RH threaded muzzle accepts the included multi-baffle brake or other standard AK-74 pattern devices. The side rail on the left receiver wall provides quick attachment of Bulgarian and aftermarket optic mounts without altering the firearm.
The pistol retains the factory side-folding hinge block, allowing an end user to install a compliant stock where legal, while the ribbed black polymer handguard stays cool under sustained fire. A hood-protected front post sight and 500 m tangent rear leaf give dependable iron sight alignment out to practical distances.
Because importation of Bulgarian AK variants in 5.56 NATO has been intermittent, the SLR-106UR is sought after by collectors. The presence of original Bulgarian Circle 10 magazines further enhances its desirability and keeps the pistol 922(r) compliant out of the box.
