The SIG551-A1® is a semi-automatic, American-built version of the SG 551 currently in service with the Swiss Army. An adjustable, 2-position gas piston operates a rotating bolt, giving long service life and reliable operation in the most unforgiving environments.
Featuring the trademark 550-series flash suppressor, genuine Swiss forearm, folding buttstock, and distinctively translucent curved magazine give the SIG551-A1 its authentic look. Additionally, the upper and lower have a custom grey finish, similar to the original SG 550-series.
An M1913 Picatinny top rail allows the operator to mount any number of optics. Included is a rotary diopter sight, calibrated from CQB distances out to 300 meters.
