60 Degree Shark Hopup Bucking (SAH60)

60 degree rubber is softer than normal 80-90 degree rubber. It is much easy to install and operate the softer rubber bucking. The B.B. will shoot out easy without any problems such as double-feeding.

Included are: 2x rubber/silicon hopup bucking and 2x fishbone spacers. Designed to seal the air tightly and prevent double feeding.
