Other milled-receiver AKs are machined from bar stock but Arsenal’s 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 Arsenal’s meticulous attention to detail delivers a receiver of unequalled strength precision and durability. - Caliber: 5.56 x 45 mm (.223) - Total length: 36.5 in.
