So after last nights cleaning of the wood Murphy provided I get to it. All of it fits without modifications. There are some differences though:
Murphy's stuff is on the left of each specimen. The rear handguard that came with the rifle has metal on it to protect the rear sight. No such thing on the handguard on the left. The buttplates are totally different. No big deal. Its not like I am going to throw the old wood in the fireplace. So for now another round of Murphy oil soap!
