Don't forget the Chopsticks little brother, the small bamboo skewers used for grilling. They are great for cleaning smaller areas and parts.

In answer to the question posed several posts above. You adjust the FRONT sight in the opposite direction that you want the bullet impact to move.

If you are using a gun with an adjustable rear sight. Rear sights are adjusted in the same direction that you want bullet impact to move.
