Weapon care
Oil, a kit, not a prayer
Short answer
Guns wear. Cleaning kits exist. Ruined is litter. See item-condition.
Also: cleaning kit · oil
How it works
Weapon cleaning kits and oil keep a gun from becoming a stick. This is not a durability table.
What to do
Clean when you can. Don't wait for the jam in a stair.
Don't
Don't invent hit-points per AK.
