The SA-A03 assault rifle replica by Specna Arms is made largely of a uniform zinc and aluminum alloy, with the use of steel elements in the most vulnerable points of the replica (steel elements - all the screws, pins and tactical sling swivels). The battery-operated SF stock and the pistol grip were made of polymer plastic. The replica's body and the RIS rail set have been anodized, which guarantees a high degree of protection against corrosion. The painting of the replica itself was made by powdering, after the surface was sandblasted. This ensures a much higher than usual abrasion resistance of the applied paint.
