Description
The Sig Sauer Electro-Optics Alpha3 scope mount/ring combo is a one-piece aluminum mounting platform built to securely clamp a 34mm tube riflescope to a 1913 Picatinny rail. Machined from aluminum with titanium hardware and finished in a protective Black Anodized coating, the Alpha3 is engineered to hold zero under recoil and resist the elements in the field.
This model sits at a 1.535″ mount height with a 0 MOA built-in offset for a true centerline-over-bore hold, keeping your reticle elevation tracking consistent across the magnification range. The integrated ring caps cinch down evenly over the scope tube, so you get the rigidity of a one-piece mount without having to marry a separate base and rings. At 7.50″ overall length the Alpha3 spreads clamp load across the rail interface while staying light on the rifle.
Covered by the Sig Sauer Electro-Optics warranty, the Alpha3 is designed around modern 34mm tube precision optics and pairs naturally with the brand’s Tango-MSR and other quality 34mm riflescopes.
