The Spyder Xtra is a great starter gun for the player who wants an upgrade. This paintball marker is semi-automatic, so it will shoot one ball per trigger pull. The Spyder Xtra comes standard equipped with a threaded clamping feedneck to keep your hopper on securely. A Tool-Free Striker Plug has been developed to alleviate the need for tools while performing basic maintenance on the marker. Spyder paintball guns are known for their ease of maintenance, great value, and shooting performance.
