You will earn 46 loyalty points with this purchase

Ruger scope mount rings are supplied as single mount rings - NOT pairs

This is due to design the M77 Hawkeye requires 2 different size mounts to create a flat base

For 1" tube scopes

  • For scopes with upto 42mm objective lens choose one size 4 and one size 5
  • For scopes with upto 52mm objective lens choose one size 5 and one size 6

Can also work with other Ruger M77 models that require different size mounts but the colour will not be the perfect match.
