Restocking model 70 any thoughts

Place an order with Manners or McMillan and get it the way you want. Thats the best option IMO, unless you happen to find an old take off stock from a FN SPR like I did...

Your M-70 SA should drop right into an SPR cut McMillan or Manners stock. Your M-70 likely has a hinged floorplate, so specify that as SPRs also come with a different bottom inlet DBM/TBM. Either the DBM or TBM should feed the .22-250 just fine if you wanted to change magazine type. If not, just specify hinged floorplate, McMillan has that pattern, too.
 
I have had both Manners & McMillan. Stocks are the same quality with pretty much the same service. Manners used to be quite a bit faster but I understand that may not be so anymore. McMillans unwillingness to respond to market demands CREATED the success of Manners stocks.
