It is not necessary to clean the barrel after every use. Cleaning frequency depends on several factors, including the number of rounds fired, the caliber, the ammunition used and the conditions in which the rifle is used.
An unusual decrease in accuracy or a significant buildup of residue may indicate that cleaning is required.
After using the rifle in rain, snow or very humid conditions, we recommend thoroughly drying, inspecting it and applying a thin coat of protectant before storage.
