Item Description
Bryant Ridge Co. is pleased to present this HOLY GRAIL semi-automatic rifle today for a penny-start auction; this is the Swiss SIG Arms SG 550-1 SP!
The SIG SG 550-1 SP stands as one of the ultimate "holy grail" long guns in modern foreign military rifle collecting due to its vanishingly small import numbers and legendary Swiss heritage. Manufactured in Neuhausen, Switzerland by Schweizerische Industrie Gesellschaft (SIG), the SG 550 was adopted as the Sturmgewehr 90 (Stgw 90) battle rifle, earning a world-renowned reputation for combining Kalashnikov-level gas-piston reliability with Swiss clockwork precision. Before the 1989 U.S. Import Ban permanently restricted foreign semi-automatic tactical rifles, SIG Arms Inc. in Herndon, Virginia imported a tiny test batch of true factory civilian SG 550-1 SP sporting models. Historical import records and collector consensus confirm that fewer than 50 total green-furniture SG 550-1 SP rifles ever entered the United States. Serial number 80020 (receiver stamped 0020) represents an extraordinarily low serial number from that original pre-ban batch, and when paired with its original aluminum transit flight case and period-correct Hensoldt Wetzlar ZF 6x42 BL optic, it exists in a tier of extreme rarity that rarely surfaces on the open market.

Condition: This example remains in extraordinary, high-grade condition, showing crisp original factory finishes and pristine synthetic furniture throughout. The signature Swiss matte gray-green Ilaflon coating on the receiver shows virtually no visible handling wear, preserving sharp, unmarred roll marks and clean factory stampings. The OD green polymer stock, ventilated handguard, and pistol grip are immaculate, retaining their original high-tack texturing without scuffs, cracks, or fading. The Hensoldt Wetzlar ZF 6x42 BL optic retains bright, clear glass with a clean reticle, and the included aluminum flight case and accessories present in fantastic overall shape.
Bryant Ridge's Analysis:
The SIG SG 550 series stands as the undisputed pinnacle of cold-war era battle rifle engineering. Developed in Neuhausen, Switzerland by Schweizerische Industrie Gesellschaft (SIG) to replace the Stgw 57, the SG 550 was adopted by the Swiss Armed Forces as the Sturmgewehr 90 (Stgw 90) in 1986. Combining the unyielding mechanical reliability of a Kalashnikov long-stroke gas piston system with Swiss clockwork precision, the SG 550 achieved unmatched accuracy and operating smoothness. Prior to the 1989 U.S. import restrictions, SIG Arms Inc. in Herndon, Virginia imported a minuscule quantity of true Swiss civilian semi-automatic sporting rifles designated as the SG 550-1 SP (Sporting/DMR). Historical records confirm that fewer than 50 total original green-furniture SG 550-1 SP rifles were ever brought into the United States. This exceptional example, serial number 80020 (with receiver serial 0020), represents one of the lowest serial numbers and rarest pre-ban Swiss military rifles in existence. It exhibits the classic Swiss matte gray-green Ilaflon finish, folding polymer buttstock, integrated folding bipod, and match-grade trigger assembly. Mounted atop the receiver is a highly desirable, period-correct Hensoldt Wetzlar ZF 6x42 BL sniper optic (Serial #162518) on an original Swiss quick-detach scope mount featuring crystal-clear crosshair optics. Complete with its original factory silver aluminum flight transit case, clear Swiss translucent polymer 20-round magazine, green sling, and factory documentation/stickers, this unit offers an unprecedented opportunity to acquire what is widely considered the ultimate grail of foreign semi-automatic rifle collecting.
