Modify Baton Ryosoku Straight Jumping Rubber (GB-05-63) and Presser

Modify's straight-style special hop rubber. The rubber is suitable for use with normal AEG-type precision barrels. The inner surface of the rubber is completely devoid of the normal hop-up knob. A special flat-shaped presser is included, which gives the rubber more effective pressure on the barrel side and thus a more effective hop-up effect on the bullet. Also excellent for R-hop tunings, for example.

Hard rubber is more suitable for higher tunings and heavier bullet weights, soft rubber is better suited for lower power and lighter bullet weights.

Designed in Japan, made in Taiwan.
