Fantastic quality! Superior high precision hop chamber replacement - you won't get better than this.
Please note, this is for the upgrade hop unit only, the upgrade precision inner barrels are separate and can be found HERE. You do not need an upgrade barrel to use the hop unit, it works perfectly well with the original or pretty much any other brand of inner barrel.
