The SIG SAUER Alpha MSR mount is a one-piece cantilever scope mount purpose-built for AR-pattern flattop receivers, holding a 30mm-tube optic at the correct height and forward offset for proper eye relief on a modern sporting rifle. Machined from aircraft-grade aluminum and finished in black, it eliminates the alignment headaches of two-piece rings and gives your scope a rigid, return-to-zero-friendly foundation. If you're putting a magnified optic on an AR in one clean, torque-and-go package, this is the straightforward way to do it right, from a company that builds optics and mounts to run together.
