Depends on what they are. Could be choke markings, proof mark, etc..
Markings typically include model, The Remington trademark, date of manufacture, test marks, inspectors, and proof mark. In some cases it may be a factory repair mark, or indication of Magnaflux testing. See the link below for an illustration of barrel code markings. Note these are for REMINGTON only.
