Prometheus Hopup Tensioner Bridge Flat Rubber Nub

Prometheus Hopup Tensioner Bridge Flat Rubber Nub. A unique set, with the little bridge (underneath) that works in all airsoft AEGs (not the Uzi). Includes both a hard and soft unit, so you can decide which one works best. Or use in two guns. A new high quality product from Prometheus in Japan! Highly recommended. Sold separately here - the tiny steel pin that fits in the center hole perfectly (optional; not needed).AKA the Namazu hopup nub metal pin - may need to be filed down slightly for a flush fit with the prometheus.
