BT Paintball offers the 10-Round magazine from the SA-17 pistol as a stand-alone accessory. It is useful as a quick reload for the pistol or as a low profile feed system for most BT markers. The feed tube holds ten .68 caliber paintballs and can be mounted forwards or backwards to meet your needs. The magazine replaces the Picatinny mounted feed elbow of our BT markers for simple installation. The elbow design makes for quick reloads using standard 10-round tubes.
