Prometheus Black Hop Rubber (Extra Soft)

Laylax (Prometheus) - Hop Up Rubber & Nub - (Extra Soft, Black)

Optimized for Flat and R-hopping

This is a tried and tested design, as good as the original Tokyo Marui design but with a longer-lasting, more durable and better gripping material. This hop rubber is designed to fit better in an Airsoft rifle hop unit with less air loss due to improved air-tightness.
