There is a company called Stockade Stocks. He mainly specializes in stocks for Savages, but he can inlet for Rem. 700 actions. He offers a money saver stock that gives you a fully aluminum bedded composite stock. It's a drop in too. All you would have to do is some sanding, skim coating to fill some minor pin hole in the epoxy coating and paint. They are very nice stocks and offer several different models. That might be a way to go. Here's the website:
Looks like there may be an extra charge for Remingtons, but you could call and talk numbers with Kevin Rayhill. He is the owner of the company. Choates are a very good money saving option. There new Tactical stock has gotten some good reviews. Might want to look into that.
Here is another option. You can stiffen up the stock that comes with the rifle. You could get it bedded in Devcon or Marinetex, and have some arrow shafts or steel rods bedded in the forearm. That will stiffen it up considerably and will cost nothing more than materials and your time. Just a thought.
