The Arsenal SAM7K ASR SBR Plum is the Suppressor Ready version of Arsenal’s milled short-barreled AK in 7.62x39mm, finished with plum handguards, pistol grip, buttstock and 10-round magazine (brand part no. SAM7K-28PASR). ASR rifles are a limited run that Arsenal hand-selects and individually inspects for bore-to-thread alignment, then tests with select suppressors from leading makers to verify concentricity. Each one is engraved with the letters ASR to mark that status. Underneath, it is the same SAM7K: a receiver milled from a hot-die hammer forged blank, an 8.5-inch cold hammer forged chrome-lined barrel and a Krink-pattern threaded front sight block. It suits a shooter who plans to run a can on a short AK and wants the alignment checked at the factory.

Key Specifications

• The chambering is 7.62x39mm, a cartridge that runs well suppressed, especially with subsonic loads.
• Barrel length is 8.5 inches, cold hammer forged and chrome lined.
• The front sight block is threaded 24×1.5mm right-hand in the standard Krink configuration.
• ASR inspection means each rifle is hand-selected, checked for bore-to-thread alignment and engraved ASR.
• The receiver is milled from a hot-die hammer forged blank, which Arsenal credits with stronger, finer-grained steel.
• The buttstock is CNC machined aluminum on a 1913 Picatinny attachment, with an ambidextrous cheek rest, four QD ports and a rubber pad.
• The fire control group is the FIME FM-922EUS enhanced group, with shortened trigger travel and a smooth pull.
• Overall length is 27.13 inches, compact enough for vehicle carry and tight spaces.
• Weight without a magazine is approximately 6.49 pounds, before a suppressor adds its own.
• Furniture color is plum across the handguards, pistol grip, buttstock and the included 10-round magazine.

Frequently Asked Questions

Does the ASR marking guarantee my suppressor will fit? No. Arsenal notes that suppressor and mounting designs vary between manufacturers, so compatibility with any specific suppressor is not guaranteed; verify fit and alignment before installation and use.

What does ASR stand for? Arsenal Suppressor Ready. These limited-edition rifles are individually inspected for bore-to-thread alignment and engraved with the letters ASR.

Do I need ATF approval to buy this? No. As of October 9, 2026, ATF no longer requires Form 4 approval, registration or a tax stamp for short-barreled rifles. It transfers on a Form 4473 with a background check through a Class 3 (SOT) dealer. State and local laws still apply. Taking an SBR across state lines still requires an approved ATF Form 5320.20.
