MIYAGAWA GOMU Wide Hop-Up Bucking EPDM 50 Degrees 2pcs for Airsoft GBB

Product description Rubber for wide barrel: EPDM hardness 50

Miyagawa rubber's long hanging series is a system that applies resistance to BB bullets longer than normal packing with two long protrusions.
The long-hanging specification makes it possible to apply a stronger hop rotation than ordinary packing, and at the same time, the effect of holding two points reduces left and right blurring, dramatically improving elasticity collection.
