Hop Up Tensioner Prometheus Flat

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 and consistent 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. 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.
