Our Assessment: This SIG 556 SWAT Patrol California-compliant edition is a semi-automatic 5.56×45 NATO rifle built on the SIG 556 platform, itself a civilian adaptation of the Swiss SIG SG 550 series. The SG 550 was originally developed as a modernized, gas-piston evolution of the AK-47 concept, featuring a long-stroke piston system, rotating bolt, and improved accuracy and ergonomics over its Soviet predecessor. This SWAT Patrol model carries a 16-inch barrel with a 1:7? twist rate aluminum receiver, reduced-length quad-rail forend with a full-width top rail, fixed stock, A2-style flash hider, and bullet-button magazine release which used to be California compliant.
Functionally, the rifle combines the proven piston-driven reliability of the SIG 550 design with modern patrol-ready enhancements, including balanced handling for close-quarters work, modular accessory mounting, and ergonomic controls. Accuracy is typical for a 16? 5.56 platform, and the system is easy to disassemble and maintain. Owners should note that the bullet-button design reflects older California regulations, which have since evolved, so current legal requirements should be confirmed before purchase or modification.
