Sig Sauer ALPHA3 Tactical 30mm Scope Mount, Super High 1.535", 20 MOA, Black Aluminum
$229.99
The Sig Sauer ALPHA3 Tactical 30mm scope mount is a precision-engineered rail mount built for hunters and precision shooters who demand rock-solid optics stability. This super high 1.535" riser puts your 30mm scope tube at the exact height needed for co-witnessing with backup iron sights or simply optimizing your cheek weld and sight picture on modern tactical and hunting rifles. The integrated 20 MOA cant is pre-angled into the mount itself, giving long-range shooters extra elevation adjustment range without burning through your scope's internal turret travel—a smart move if you're pushing shots past 500 yards or running a scope with limited elevation adjustment.
The ALPHA3 is machined from Sig's proprietary steel alloy with a precision that balances toughness and workability. That matters: the rings need to clamp your scope securely without crushing it. The epoxy powder coat finish stands up to gun oils, solvents, outdoor weather, and the general abuse that comes with field use. Weaver-style steel clamps provide the clamping surface, giving you broad compatibility with any modern picatinny rail system. Installation is straightforward with standard torque specs—the mount secures to your rail at 65 inch-pounds, and the scope rings tighten to 25 inch-pounds with a T15 Torx driver.
Sig backs the ALPHA3 with their Infinite Guarantee, so you're covered for defects in materials and workmanship. This is a no-frills, no-compromise mount: it does one job and does it well, whether you're running a 3-12x hunting scope or a high-power tactical optic. Straightforward, reliable, and built to last.

Frequently Asked Questions
Will this mount work with my AR-15 or modern rifle?
Yes—the ALPHA3 is built with Weaver-style steel clamps that are compatible with any standard picatinny rail system found on modern tactical rifles, AR platforms, and many hunting rifles.
What does the 20 MOA cant do?
The 20 MOA angle is built into the mount itself, giving you extra upward elevation adjustment for long-range shooting without using up your scope's internal turret range. This is especially useful if you're shooting past 500 yards or using a scope with limited elevation throw.
What torque specs do I need to install this mount?
Tighten the mount to your picatinny rail at 65 inch-pounds using a 1/2-inch nut. Secure the scope rings to the mount at 25 inch-pounds with a T15 Torx driver. Don't over-torque—proper specs prevent damage to both the mount and your optics.
Is this mount covered by any warranty?
Yes. The Sig Sauer ALPHA3 is backed by Sig Sauer's Infinite Guarantee against defects in materials and workmanship.
