Shooting sticks (weapon mount)

Shooting sticks are portable weapon mounts commonly used with rifles to brace the weapon on the ground, walls, and other features of the local terrain in order to provide a stable resting position to shoot from; reducing user fatigue and increasing potential accuracy. They are popular with field shooters, such as hunters and snipers, and with metallic silhouette competition shooters using blackpowder rifles.
