Pro Team Paintball's Clear Tac Cap II is like many other tac caps for Cyclone hopper systems.  This hopper reduces the profile of your paintball gun, maintains the tactical look, and replicates a limited ammunition capacity of a real firearm.  This Tac Cap hopper will hold 43 paintball (plus one in the chamer if you count that).  The Clear Tap Cap II has a clear plastic body so you can see how many paintballs you have left on those days you loose count while counting to 43.   The to lid cap is black.
