About the SIG 550 SP

The SIG 550 SP represents the civilian import variant of Switzerland’s iconic Stgw 90 service rifle. Imported in very limited quantities before the 1989 import ban, these rifles are prized for their Cold Hammer Forged barrels, folding stocks, diopter sights, and exceptional Swiss manufacturing standards. Collector interest is strongest in rifles that remain unmodified and complete with original accessories.

SIG 550 SP Pre-Ban Values & Variants

Pre-ban SIG 550 SP rifles are valued for their documented era and how closely they remain period-correct. Most examples range from $6,000 to $8,000, depending on originality, condition, and demand in restricted states.

Potential upside, but you wait for the sale, pay commissions and still carry uncertainty around final prices and timelines.
