PROMETHEUS Hop-Up Tensioner Set ( Bridge )
Longer pressure surface than conventional tensioner, along with rounded bottom profile to achieve sufficient hop up with lower pressure, optimized for high firing rate AEGs.
Notched bottom surface for more consistant BB trajectory, thus tighter grouping
Soft and hard type included
Works best with Prometheus Straight Chamber Packing series
Suitable for most Marui-Compatible AEGs ( Except UZI )
