Sig Sauer
The Sig Sauer ALPHA3 Tactical 30mm scope mount is a super-high ring system built to hold precision optics securely on your rifle without damage. Machined from Sig's proprietary steel alloy, these rings strike the balance between strength and workability—they clamp firmly around your scope tube yet won't mar or crush quality glass under proper installation. The 1.535" height positions your optic for co-witness or absolute-top-of-rail setups, making this mount a solid choice for tactical rifles, long-range builds, and hunting platforms where you need repeatable zero and confidence in your glass.
What sets the ALPHA3 apart is attention to the details that matter in the field. The steel rings feature Weaver-style clamps, so they'll work with standard picatinny rails found on most modern rifle uppers. A durable epoxy powder coat protects against oxidation, gun oils, solvents, and the weathering that comes with backcountry use. The 0 MOA configuration keeps your setup true to your rifle's natural sight plane.
Installation is straightforward with the included torque specs: 65 inch-pounds to the rail and 25 inch-pounds (T15 Torx) to the scope itself. Dial it in right and you won't second-guess your zero. Backed by Sig's Infinite Guarantee, the ALPHA3 is engineered to last—no excuses.
