Unique centertube features a threaded collar that allows you to tightened the stock to the back of the marker to prevent stock wobble. The rear of the centertube houses a threaded end-cap which allows for access for parts or small parts storage. The stock body can be removed from center tube and used on other marker-specific, commercial-spec center tubes. The right equipment for any M4 themed paintball marker. The best car stock we have for the A5.

Works with all A5 paintball guns ever created, including the new 2011 A5's along with any other paintball gun that accepts the A5 style stock adapter.
