Cool little 6.5" CQB version of one of the most popular paintball barrels ever made. JJ Ceramic barrels use the most advanced technology available today. While the ceramic is being applied, teflon is injected into the pores of the aluminum, resulting in the slickest, yet most durable surface in the world. These barrels are quiet, light and accurate. The 6.5" version is available in the A5/X7/BT-4 thread. Also works on the TiPX Pistol.
