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

If you enter quantity 1 when you buy you will buy ONE ring - NOT a pair. For a pair enter 2. This is because some models (M77) require different heights front and back. Others such as 10/22 take the same size making it a lot easier!

Please read fitting carefully. Mount returns due to choosing the wrong size are WAY too common - cost us both - and are so easily avoidable! If unsure please ask....Please read the fitting and compatibility info below.
