The Arsenal SAM7K-44 AK-47 pistol w/ quad rail is a truly high-quality 7.62x39 pistol which is rarely found on the American market. Each receiver is milled from a hot-die hammer forged receiver blank by the Arsenal Co. of Bulgaria. This produces stronger and fine-grained steel than that of other AK receivers. (Standard Krink configuration with 24x1.5mm RH threads) This pistol ships with one 5 round magazine.
