(M) RARE SWISS SIG SG 550-2 SP SEMI-AUTOMATIC RIFLE WITH HENSOLDT OPTIC.
Manufactured in Switzerland and imported by SIGARMS in limited numbers, likely only a few hundred. The 550-2 SP was introduced around 1990 as a semi-automatic variant of the well regarded SIG 550 series of assault rifles. The matte finished barrel has an integral cage flash hider. Hooded blade front sight with flip up night sight mounted to the adjustable gas block. Drum style rear sight. In addition to the factory iron sights, this rifle is also equipped with an appropriate green finished Hensoldt ZF 6x42 BL scope with intact rubber lens cover and eye cup on a quick detach mount as could be ordered with these rifles. Gray enamel finished stamped construction receiver with "BP" Swiss proof and standard legends. Externally visible numbers are matching. Furniture includes a ribbed olive forend with folding alloy bipod, ribbed olive pistol grip, and side folding olive stock with cheek riser. Includes sling and manual. No magazine is included, although these rifles accept standard SIG 550 series magazines. CONDITION: Excellent. Nearly all of the factory finishes are retained with light handling marks and a small rub behind the ejection port from ejected brass. Stocks are very fine with a few minor rubs. Very good, well defined bore with razer sharp rifling. Fine mechanics. Clear optics. An outstanding, very hard to find scoped Swiss rifle.
