Can this be done?

With enough filler, epoxy, machining and time most anything can be done. The best bet is usually to sell the prospective donor and buy what you need.

I'm way to lazy to look up and compare all the dimensions. But, depending on the starting stock material it can be a real pain to get epoxy to bond too it. I always try and work in a mechanical bond as well as the chemical one.

Like Bob I would start over.

Well it will be easier to go from R700 to M70 than the other way.

However, the very reason it will be easier might also mean you fuck the stock. Taking it from R700 to M70 will mean removing a lot of stock material. The potential problem is many of these stocks have a type of foam filler in them and you could end up cutting away a lot of the fibreglass.

As has already been posted.....sell it and buy a stock for the M70.

That's true; best to sell it and buy the right one because if/when you mill through the epoxy layer and hit the foam filler, that will be harder to manage. Not saying you can't do it.

The M70 action depth is greater than a 700, meaning you will have to add about .200 to the bottom of the stock for a flush fit of the trigger guard and magazine box. It is not an easy conversion, but I have done worse.

Thanks Gents,

A few 700 stocks will be in the Classifieds this weekend.
