You can swap the stocks back and forth by yourself.
It only takes about 2 minutes... you will need.
1. phillips screwdriver to remove the forearm and the buttplate (or pad)
2. ratchet and a 9/16" (or 14mm) socket and long extension to remove the stock from the action.
Take the screw out of the bottom side of the forearm and pull it off.
To remove the stock just stick the socket and extension down into the hole in the stock and unscrew it.
Put the other set on it it's place and tighten everything up.
The bolt for the thumbhole stock is in the thumbhole so you don't have to take the buttplate off.
