This JB3D printed Adjustable butt hook is designed for the GRS Stocks. 

The hook can be adjusted up and down and the wings and links can be adjusted to the angle you need for a comfortable shoulder. This screws into the original holes on the stock very easy to fit and the original up and down adjustment can still be used.

Please select Wings or Wings and Extensions from the drop down menu.

Please note, these hooks are only compatible with GRS stocks that have the adjustable extending butt plate.

Extra extensions can be purchased separately to add more adjustability or upgrade your hook to the extended version.
