The Arsenal SASM7K (Arsenal part no. SASM7K-85) is part of Arsenal’s limited-edition AK-20 custom shop line, re-imagining the classic AK platform as a factory short-barrel rifle. It’s hand-built with a milled receiver, hammer-forged chrome-lined barrel, and aircraft-grade aluminum handguard, chambered in the reliable 7.62x39mm round. Its proprietary integrated gas system lets you toggle between ammunition types and firing conditions, and it wears an AR-15-type telescoping stock rather than a traditional AK stock for a more familiar, adjustable length of pull.
