In what position should firearms be stored to prevent oil accumulation?

Storing firearms horizontally or with the muzzle pointing down is the best position to prevent oil accumulation. When firearms are placed in this way, any excess oil can drain out of the action and the barrel, reducing the risk of it pooling in areas that could potentially affect the firearm's performance or cause corrosion.

This storage method also helps maintain the integrity of any lubricants applied, ensuring they remain effective without creating a mess or attracting dust and debris. The other options, such as storing firearms vertically or in any random position, can lead to oil buildup that may negatively impact their functionality and safety.
