I picked up a Marlin X-7 in .223 a few weeks ago for a song. Davidson's had them through my local dealer on sale for just $230.00, so I couldn't pass it up. After I got it home I wasn't very happy with the cheap, thermoplastic molded stock it came with. It was "functional", but that was about it.
So I picked up a Boyd's Laminated Featherweight Thumbhole for just $99.00. The fit was perfect. The barreled action just dropped right in. It really makes the whole rifle look and fit so much better. I'm thinking of picking up one for one of my Mosins. I'll keep one original. The only thing is you have to remove the front sight in order to get both of the 2 barrel bands off the barrel. I'm really tempted because Boyd's makes a hell of a nice stock for the money. You can get them in several different colors as well.
