The TeleDart CT11 Cleaning Brush is a barrel and blowpipe cleaning tool designed for use with TeleDart projectile systems that use 11 mm calibre barrels or blowpipes (such as B9, B11, and similar TeleDart blowpipe/projector models). It helps remove debris, powder residue, dirt, and moisture from the inside of your barrel after firing, ensuring smooth airflow and consistent dart performance. Regular cleaning with the CT11 brush helps maintain accuracy and prolong the life of your TeleDart equipment.
