Built on a Bulgarian 1 mm stamped receiver, this SLR-107R follows the AKM pattern and carries the Arsenal, Las Vegas, Nev., U.S.A. importer mark with "Made in Bulgaria" markings. It retains the original left-side optics mounting rail and replaces the factory top cover with a continuous Picatinny railed cover that hosts a flip-up rear aperture sight, paired with the AKM front sight block.
The 16.25 in barrel is cold-hammer-forged and chrome-lined for durability and easy maintenance. It uses standard 14x1 mm LH muzzle threads and comes fitted with a JMac Customs micro KeyMount 14F brake that supports the KeyMount/KeyMicro interface. The bore is clean and mirror-bright with sharp rifling.
Up front, a Midwest Industries extended M-LOK aluminum handguard provides generous mounting space. Short Picatinny rail sections are installed at 6 o'clock, and a detachable bipod with a rail adapter is currently mounted, giving stable support when needed.
Ergonomics and control upgrades include an ALG trigger for a refined pull and a Dissident Arms extended safety for easier manipulation. The B5 Systems collapsible stock with cheek riser rides on a carbine receiver-extension adapter, offering multi-position length adjustment (approximately 11.75–15 in LOP) and QD sling sockets.
Sling setup is enhanced by a tube-mounted, 3-point sling attachment at the receiver-extension end plate, paired with a single-point sling. The rifle is configured for standard 30+1 capacity in 7.62x39 and ships with a total of six magazines in 30-, 10-, and 5-round sizes. The original unrailed, matching-number top cover (last four 2629) is included for those who prefer a factory-style configuration.
