ASG 16065 HOP-UP RUBBER SHARK BUCKING 60 DEGREE BLUE X2

60 degree rubber is softer than normal 80-90 degree rubber. Much easier to install and operate. Shark Hop-up Bucking was originally designed to prevent double feeding. By having 3 special “fins” inside the bucking, Shark Hop-up Bucking can hold one and only one B.B. tightly in the chamber.
