Thanks!
I think I'll just do the reoil lug recess, the receiver ring and tang. What really suprises me (and scares me) is that there isn't any kind of recoil support in the Remington stock such as a recoil crossbolt.

The rifle is an ADL also, and I'm going to try to reinforce the wood at the bottom of the magazine- its only about 1/8" thick, which to me seems very fragile.
