Not for sure. I've heard of guys replacing their furniture with genuine WWII stuff. For that authentic look.

There's not a lot of fit involved and I have to assume it works.

But I got nothing solid to confirm it just heresay. If Ghostsoldier is about he'll know.

I have 3 sets of furniture for mine. I saved the original when I wanted to shorten the buttstock. So I got a Boyds along with a horizontal forend. Cut a full 2 inches off the stock and I could cut more, just too long for me.
The forend is just a different screw. Long one for the pistol grip, short one for the horizontal.
