DYE Barrels set the standard for accuracy and quality nearly 25 years ago and continue to do so today. DYE’s new UL-S Barrel back gives you more control and more accuracy with an extended 7 inch control bore. The UL-S control back uses multi-stage precision honing, the most accurate and consistent finish available in paintball, eliminating ball spin, and improving accuracy. Self-aligning two piece construction ensures properly centered assembly between control bore and steady port tip. This combination of precision components provides an extremely quiet shot, superior accuracy, and total performance. The DYE Ultralight Barrel System is designed to give you the ability to easily change barrel length and bore size to match your performance needs. 8” barrel back 7" control bore 5.7 grams lighter than standard UL back Autococker Quick threads Compatible with all DYE barrel tips Bore size: .684"
