20" Tippmann A5 X7 J&J Ceramic Sniper Paintball Barrel
The J&J Ceramic is actually an aluminum paintball barrel with a special ceramic and teflon coating to give it a super-slick low-friction surface. While the ceramic is being applied, teflon is injected into the pores of the aluminum, resulting in the slickest, yet very durable surface in the world.
A paintball rarely breaks in this barrel, and when they do, you can just keep firing to clear the barrel (that?s the "self-cleaning" in action). These barrels are quiet, light, and accurate.
