SIG Sauer SIG556R

posted on July 29, 2013

Built off of the SIG556 platform, which itself is a modified version of the legendary Swiss SIG550 military rifle, the SIG556R is chambered in 7.62x39 mm and can take most standard AK-47-type magazines.

Thanks its SIG550 lineage, the 556R has a folding stock, which, when folded, cuts the rifle’s overall length to a mere 26 inches, making storage and maneuverability a cinch.

The piston-operated 556R’s charging handle is on the right side of the rifle, just like on an AK, but its safety selector is located above and in front of the pistol grip, similar to that of an AR, which is far more ergonomic.
