Want to increase the range and accuracy of your AEG ?
One of the most simplest upgrades you can perform on most AEG's to increase the performance is by installing a good hop rubber.
Properly one of the best on the market at the moment is the hop rubber from Maple Leaf these hop rubbers have a ridged outer to seal tighter into the hop chamber providing a better seal and a new design of hop that when used with the matched Maple leaf hop nub can give a marked improvement on range.
They are available in different degrees of hardness which give you the ability to match the right rubber to the FPS of your AEG.
