Hop Up Tensioner Prometheus Bridge

This Prometheus Flat Hop Up Tensioner is made with minimal tolerances from a hard wearing and oil resistant material.

Thanks to the slightly concave underside, the Prometheus Flat Hop Up Tensioner offers a wide area of contact with the top of the BB, making the hop-up action start at the same point and with the same amount of friction every time. The bride-shape provides a very consistent distribution of weight. This will absolutely improve accuracy.

There’s a hard and a soft hop-up tensioner enclosed in this package, so you can experiment yourself which one will fit best with your replica and the BB’s used.
