Apart from cleaning your firearm the next most important maintenance step after cleaning is to ensure that your firearm bore is lubricated with the correct oil for storage. You need to eliminate any possibility of corrosion occurring during storage. Many bore oils being sold in the market place or alternate products recommended for this purpose do not offer the correct short or long term protection required with many showing signs of breaking down within two weeks of application leaving your firearm bore in an unprotected state. This can cause significant corrosion damage. The product you can rely on to protect your firearm bore over short & long term storage is Helmar H9500 Bore Oil. It has been specially formulated for this task.
