Sig Sauer ALPHA3 Tactical 30mm Scope Mount - Super High (1.375"), Black Aluminum, 0 MOA
$229.99
The Sig Sauer ALPHA3 Tactical 30mm scope mount in Super High (1.375") configuration is a precision-engineered ring system built for serious rifle setups where mounting height and clearance matter. Whether you're running a large-objective optic, pairing your scope with a night vision system, or need extra rail clearance for co-witnessing accessories, this mount positions your glass exactly where it needs to be. The ALPHA3's proprietary steel alloy construction strikes a balance between rigidity and ductility—stiff enough to lock your scope solid, forgiving enough not to crush expensive glass if you torque carefully.
Sig's manufacturing precision shows in the Weaver-style clamps, which are machined to form snugly around your 30mm tube without the flex or wobble you might encounter in budget rings. The epoxy powder coat finish stands up to gun oils, solvents, and extended field use without flaking or corroding. This is a mount that works equally well on a precision long-range rifle, a tactical platform, or a hunting rifle where you need extra vertical real estate. At 0 MOA, the rings sit level to your rail—no built-in elevation for paper shooting or ballistic compensation.
Installation requires respecting the specified torque specs: 65 in-lbs to the rail via the 1/2-inch nut, 25 in-lbs to the scope rings using a T15 Torx wrench. Stay within these numbers and your setup will hold zero shift after shift. The ALPHA3 line carries Sig Sauer's Infinite Guarantee backing, so if something fails in actual use, you're covered.

Frequently Asked Questions
What does "Super High" mean and will it work with my scope?
Super High refers to the 1.375" mounting height above the rail. This extra elevation is useful if you're running a large-objective or high-turret optic, or if you need clearance for a night vision device or other top-of-rail accessories. If your current scope fits in standard rings and you have no clearance issues, this height isn't necessary—but if you need the extra room, this mount delivers it without compromising clamping surface.
Are these rings compatible with Picatinny rails?
Yes. The ALPHA3 uses Weaver-style clamps, which fit both Weaver and Picatinny rails securely.
What does 0 MOA mean?
0 MOA means the rings mount level to the rail with no built-in angle. Your scope will sit horizontal to your barrel. This is the standard choice for most shooters; the alternative (angled mounts) are typically used for specific long-range systems designed around the angle.
What tools do I need to install this mount?
You'll need a wrench or socket for the 1/2-inch mounting nut (to torque to 65 in-lbs to the rail) and a T15 Torx wrench to secure the scope ring screws (torqued to 25 in-lbs). A torque wrench is highly recommended to stay within spec.
