Couple a things...
Ben, do you have a URL for those forearm levers? I couldn't find any on Brownell's site.
Next! When I was putting the synthetic forearm on my "all weather" 30-06, I noticed that the spacer was moulded in as part of the forearm. This got me to thinking....
How about I shape the rear of the walnut forarm to conform to the front of the receiver, and do away with the spacer?
I could contour a thin piece of steel or brass to protect and strengthen the rear end of the forearm...
We're just talkin looks here...
Heck! If I could I'd square off the front of the receiver and forge a tang for the back!

uh oh...
