The SAM5 rifle is extremely sought after and a very collectible firearm. Arsenals SAM5 receiver is milled from a hot-die hammer forged receiver blank by the Arsenal Co. of Bulgaria. Other milled-receiver AKs are machined from bar stock but Arsenals hot-die hammer forging produces stronger and finer-grained steel. Internal voids and cooling deformations are eliminated by the 5-ton hammer forging process. The forged receiver blank requires over 5.5 hours of milling before assembly. This forging and milling process is complex and time-intensive but Arsenals meticulous attention to detail delivers a receiver of unequalled strength precision and durability.
