A MUST HAVE for swfa ss scopes!

These stops allow setting your scope's vertical zero to whatever distance you choose, typically 100 yards, so you'll always come back to zero without having to remember the MOA or Mrad value, or relying on a paint or scratch mark. You can zip back to zero even in low light or pitch black dark. Easy as pie to setup - just get your distance mark at the range, pop the vertical cap, add one or more shims to keep the cap from going below your zero distance mark.
