Proper gun maintenance is essential for its accuracy and longevity.
Even if you don’t use your firearm often or have it for emergencies that never occur, taking care of it is imperative.
Once every couple of months or once a year, depending on the type and purpose, deep clean and re-oil it since nature doesn’t end at the entrance to your gun safe.
For a desirable effect, the quality of solvent, oil, and instruments you use for it plays a huge role as well. It might be difficult to choose great products without help from the people who’ve tested dozens of them.
