Product Description
These are for Ruger stocks that take modules,,not something you can add to a regular stock,,
without a LOT of precision work anyway,,
This is the Youth Low Comb version, 1.26" comb and 12.5" Length of Pull
They offer a Adult version too
They also offer High Comb in both Youth and Adult
I am pretty sure most of these stocks come with the Low Comb Adult module from the factory.
