Description
Product Overview
The SIG Sauer 551-A1 is a dependable semi-automatic rifle chambered in 5.56 NATO and compatible with .223 Remington ammunition. It combines the classic Swiss 551-series design with a practical 16-inch barrel, synthetic folding stock, and M1913 rail for mounting optics and accessories. The folding stock reduces the rifle's length from 36.1 inches to 26 inches, making it easier to transport and maneuver in confined spaces. A four-groove barrel with a 1:7 twist stabilizes a broad range of 5.56 NATO projectiles, while the two-stage trigger supports deliberate, controlled fire.
