Curious to see what is the best way to extend a butt stock? I have a Browning Xbolt Micro Hunter in 7-08 that was my sons when he was small. The length of pull is 12.5in and it has a 20in barrel. I would like to extend the length of pull to 13.5-14in. It would be just like a Rem model 7. It would be a great little woods gun.
