Shark Hop-up Bucking

MB HB

Shark Hopup Bucking was originally designed to help prevent double feeding.
By having 3 special "fins" inside the bucking, Shark Hopup Bucking can hold one and only one B.B. tightly in the chamber.

Fishbone nub helps to provide more equal pressure to the BB to improve backspin and accuracy.

Includes Two (2) Buckings (1 rubber/1 silicone) and Two (2) Nubs.

Price: $10.95

60 Degree Normal Bucking

Why 60 Degree?

Cons: This item may last shorter than the regular rubber.

Recommended for guns shooting less than 400 fps.
