ESCW-63
BRAND E.S. CUSTOM WORKS
HULK Flat rubber red version VSR-GBB style.
FLAT shape optimized for an absolutely optimized Hopup "backspin" effect.
This red version works best on high powered configurations or with lightweight BBs.
70 Shore PS Elastic Rubber.
This guarantees excellent friction (and backspin of the BB), durability and resistance, and prevents the pellet from blackening over time (as happens to some buckings of other brands).
100% Made in Italy.
