The Remington Model 740 semi-automatic rifle has long been out-of-production. You may be able to find an original stock on one of the firearms auction sites, like Auction Arms.com, or you might try ebay. Consider that the later model rifle stocks, like the 742, 7400 and 74 Express stocks will also fit, but will not match the 740 Model forearm pattern.
If you are referring to the magazine latch style from the Remington Model 7400, yes it can be used on the Remington Model 740, but you'll also need to use the spring that goes with the newer style. These latches (newer style) are available in varying heights numbering from 0 thru 5 so you'll need to make sure the right height/size is chosen to get correct cartridge feed in your rifle.
