My cheek piece is a new product designed to fit the Ravin R9, R10, R15 and R20 and now the R26, R29 as well.  It's adjustable in height but limited to approximately a 3/16" range.  

It's specifically designed for folks who use a Burris Oracle X or

a Ravin jack plate below their scope.  But it will benefit anyone who uses a scope that mounts higher than normal above the crossbow scope rail.

Now offering a full cheek piece for the R470/R500.

This cheek piece is taller for those folks who run out of adjustment with the standard Ravin R470/R500 cheek piece.
