Description

Shark Hop-Up Rubbers from MadBull are very suitable for tuning weapons. A special feature of these rubbers are 3 fins, which guide the ball more precisely into the hop-up unit and thus ensure better precision. In addition, the fins prevent so-called double feeds. A double feed is when two bullets are fired in one shot. This rubber has thicker walls than those of other manufacturers, which makes installation somewhat more difficult, but in return the rubber seals much better. Two rubbers and the matching X-spacers are included in the delivery.
