Prometheus Flat Hop Up Tensioner Bridge Type
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.
