This is the highly regarded Prometheus Flat-Hop Bucking in soft/blue. Designed specifically to be used with the Prometheus Flat-Hop Tensioners, this is a hop rubber/bucking without the traditional hop-mound.

When set up correctly, this hop rubber is intended to give performance similar to that of an R-Hop but at a fraction of the cost and complexity and with added reliability - nothing needs to be glued in place with these!

The blue rubber that these are made from is roughly the same durometer (hardness) as the much-loved Prometheus Purple standard-style buckings, and is optimal for AEGs firing 0.2g to 0.43g ammunition at powers from 0.8 to 2 joules - that is to say, these should work with almost any AEG setup you want.

While these buckings should be compatible with almost any inner barrel and hop-unit, please be aware that there are different dimensions and tolerances between manufacturers, so this may need modification to fit.
