Sourdough,
Midway has the Choate Survivor stock and Storearm forearm. Scope will not fit in the butt-stock, but the forearme in nice fro some storage, and the screw makes it easy to take-down. If you do not go that route, I found that the knurled screw that fits in the side of my old CB radio (to mount it) is the same thread and length for my forearm. Works well on my .243 to take it down or change barrels. (I don't have the Survivor set-up on my .243, just my 12ga and 20ga/.357mag).

I have a some on a couple of my NEFs. Work well with a small slip-on butt-pad and a Velcro shell holder.
I also like the weight of the .243, but make sure your barrel shoots well. Some of the light .243 barrels don't hold a group. Mine does now, but it took me 3 of them and finding a load she likes.
