The Unertl Sniper Scope is a fixed 10X power scope. The scope comes in two versions, the MST-100 and the MST-150. The MST-100 is intended to be mounted on the M40A1and M40A3. The MST-150 is intended to be mounted on the Special Application Scoped Rifle (SASR). Both systems encompass a mil-dot reticle that enables the sniper to estimate ranges out to 1000 yards.

The Unertl Sniper Scope has been replaced by the Scout Sniper Day Scope.
