The Dye Ultralite Barrel is a popular favorite of the top pros such as the Los Angeles Ironmen, Chicago Aftershock, Baltimore Trauma and others. The Ultralite is chosen for its all aluminum light weight advantage. It is also a very popular custom barrel because its aluminum construction offers the ability to be anodized to match any gun color. It is made with the same precision quality that you can expect from DYE as the leader in barrel manufacturing.
