Thread: Rem700 primary extraction

The easiest way to correct primary extraction issues on the M700 is to built up the cam contact point on the receiver with TIG weld and file it to the correct size. The back of the receiver is not critical for heat-treatment and, done properly, is both quick and invisible. Tape or similar must be used when welding to protect the surrounding finish, and a dab of cold blue on the finished repair will blend in nicely. Removing and rebrazing the bolt handle is difficult, time-consuming, and also affects the temper of the cocking cam.
