Upgrade your stock TPX barrel or install this barrel on your A5 for that close quarters combat look and feel. The J&J Ceramic barrel is an excellent choice for upgrading the performance of your paintball marker. J&J barrels are made from 6061 T6 aluminum then CNC machined to the highest quality standards in the industry. The ceramic coating and teflon impregnation reduces the friction rate to a minimum while inducing a self cleaning method. The smooth finish of the barrel will provide more consistent shots over a longer distance to help improve the accuracy of your marker.
