The SIG SAUER ALPHA-MSR is a one-piece cantilever scope mount for AR-platform rifles. Machined from 7075-T6 aluminum, it sets your scope at a 1.535 in centerline height and pushes it forward for proper eye relief on a flat-top rail. It is a natural match for LPVOs like the SIG TANGO-MSR, and it comes in 30mm or 34mm and Black or Coyote Brown.

Frequently Asked Questions
Which size do I need?
Match the mount to your scope's main tube: 30mm or 34mm. Most LPVOs, including the SIG TANGO-MSR 1-6x24, use a 30mm tube; many higher-power scopes use 34mm.
Will it fit my rifle?
The ALPHA-MSR is designed for flat-top AR-style rifles with an M1913 Picatinny rail. The 1.535 in height lines up well with AR stock and cheek weld.
Do you install scope mounts?
Yes. Buy your riflescope from Los Cazadores and our gunroom will mount and boresight it for free, including the rings or mount you buy with it. Ordered online? Just bring your rifle, scope and mount to any Los Cazadores store.
