SIG SAUER came clean with the 556 and owned up to its Kalishnakov roots with their new 556R. The 556 rifle has always had an AK-style action, which contributes greatly to the reliability of Sig’s rifle platform, but now Sig has released a 7.62×39 caliber version that is compatible with standard AK-47 magazines.
The rifle uses an AK style gas piston but incorporates a two-position gas valve, presumably to adjust the gas system for use with a suppressor. A telescoping stock makes the rifle easily adjustable for shooters of various sizes, and it also folds down out of the way for easy transport or CQB use. A marked improvement on the AK platform is the incorporation of an M1913 Picatinny rail to allow for the quick installation of scopes or holographic sights. Optional handguard rails increase the versatility of the platform even further, while an ambidextrous safety selector and ambidextrous rear sling mount make it easy to shoot left or right handed.
The 556R ships with a factory-included red dot aiming system.
