SIG SAUER ALPHA6 30mm Medium Scope Rings

Description

SIG SAUER ALPHA6 30 mm Medium Scope Rings

The SIG SAUER ALPHA6 medium scope ring set provides a mounting option for a riflescope with a 30 mm maintube. This black aluminum set, manufacturer part SOA63002, has a specified medium height of 0.94 inches. SIG SAUER measures that height from the top of the Picatinny rail to the optic’s centerline, a useful reference when comparing rings for objective clearance and the desired sight position.

Fit and ring height

Start with the scope tube diameter: these rings are for a 30 mm maintube, not for a scope with a 1-inch, 34 mm, or 35 mm tube. SIG SAUER specifies M1913 Picatinny and Weaver mount compatibility. The medium 0.94-inch height sits between the company’s 0.85-inch low and 1.12-inch high ALPHA6 30 mm choices. Those heights describe the mounting geometry; selecting the correct one still requires checking the scope objective, rifle, rail, and the shooter’s preferred sight picture.

A 50 mm objective marking, for example, identifies the nominal lens size, not the complete outside diameter of the scope’s objective housing. Lens covers, the barrel contour, and the rail can also affect fit. Measure the actual equipment or consult the relevant manufacturer’s guidance rather than choosing ring height based on objective-lens number alone. The ring set itself has zero MOA cant.

Construction and installation details

SIG SAUER describes the ALPHA6 rings as machined from a proprietary billet aluminum alloy intended to balance strength and weight. Its product specifications list 6061-T6 material, a Type III flat-black hard-anodized finish, and black-oxide hardened steel hardware. The manufacturer emphasizes that proper installation lets the rings hold the scope without damaging the maintube.

SIG SAUER lists 65 inch-pounds for the rail attachment with a 1/2-inch socket and 25 inch-pounds for the scope attachment with a T15 Torx tool. These are manufacturer torque specifications for this ALPHA6 product page; use suitable tools and consult the supplied instructions during installation. The manufacturer says a scope-leveling tool is included with the medium and high 30 mm mounts. Confirm package contents against the exact set received.
