RE: Mossberg ATR 100?
FWIW, I personally would much rather have the Mossy ATR 100 than the Remington 700 ADL based upon the stock alone. The Mossberg stock is much stiffer in the forearm than the Remington.
The trigger is nicer as well.
YMMV
Edit: and you're gonna have to buy a base for the Remington, the Mossy comes with bases.
