The SIG Sauer Alpha5 Scope Mount (SIG Sauer part no. SOA55004) is a one-piece optic mount built for 35mm scope tubes at a 1.25-inch mounting height, extending SIG Sauer Electro-Optics’ Alpha5 precision mounting line to the larger European-standard tube diameter. Machined to the same tolerances as the rest of the Alpha5 series, it’s designed as a matched mounting solution for shooters running 35mm-tube optics rather than the more common 30mm or 34mm sizes. The single-piece construction keeps the base and rings permanently aligned, avoiding the return-to-zero issues that come from mismatched separate components. It’s built for precision rifle shooters who specifically need 35mm tube support.
