The Arsenal SAM7K SBR Black is a semi-automatic short-barreled AK chambered in 7.62x39mm, with black handguards, pistol grip, buttstock and 10-round magazine (brand part no. SAM7K-28). Each SAM7K receiver is milled from a hot-die hammer forged blank by the Arsenal Co. of Bulgaria, a process that takes more than 5.5 hours of machining per receiver. An 8.5-inch cold hammer forged, chrome-lined barrel carries a threaded front sight block in the standard Krink configuration. The CNC machined aluminum buttstock attaches to a 1913 Picatinny rail and adds an ambidextrous cheek rest, four QD ports and a rubber pad. Black is the base color of the line, with matching black furniture and magazine.

Key Specifications

• The chambering is 7.62x39mm, the AK round with the deepest ammunition supply.

• The front sight block is threaded 24×1.5mm right-hand, the standard Krink thread for muzzle devices.
• The receiver is milled from a hot-die hammer forged blank, which Arsenal says yields stronger, finer-grained steel than bar stock.

• Weight without a magazine is approximately 6.49 pounds, light for a milled-receiver AK.
• Rifling is four grooves with a 1:9.44 twist, the rate Arsenal specifies for 7.62x39mm.
• Furniture color is black across the handguards, pistol grip, buttstock and the included 10-round magazine.
