No, unfortunately that does not appear to be an available option.

The Deal Deal by pablo, December 7, 2022
If y'all aren't really tall or you have a big recoil pad, you need to adjust your eye relief back. This is the solution. Great communication, quick shipping. I recommend. Genuine Ruger product in original packaging. Adds to value of your rifle.
