Standard hop tensioners only provide a very small point of contact with which to spin the BB. These drop in nubs provide a larger contact patch leading to better range and accuracy.

• Comes with soft and hard nubs to allow for varying power levels and BB weights.
• Bridge tensioner provides 3 points of contact for tighter groupings.
• Flat tensioner provides maximum hop effect for high power setups.

Installation notes:

• It may be necessary to trim the rubber to fit into some hop up units.
• This product is designed use with the Prometheus Straight Chamber Packing. If you wish to use a standard hop rubber it will require modification or use of an aftermarket barrel such the Orga Magnus Barrel that allows the rubber to be installed with a 90 degree rotation.
