You can request a manual from Remington on their web site.
There have never been any recalls on the Remington Model 742 that I'm aware of. The Remington 742 is now an obsolete model and was replaced with the Remington Model 7400. The bolt received an upgraded design along with the magazine catch/release. At one time Remington was offering a Model 7400 as a replacement for the Model 742, if you sent them your Model 742 along with $350.00. Is there a problem with the 742 that you have?
Follow the instructions in the owner's manual. If you don't have one, go to Remington's web site and request one.
