Help me to chose the right Hop Up chamber
I am upgrading my KJW G27, I am ordering upgrades from different stores and I need help to chose the right hop up rubber chamber.
My intention is to find the original Marui stock one, but if I can't find it on the market the chose is different; I have found the Firefly but the are sold in three variants; extra soft, soft and Hard; what is the differenze and what other upgrades influence the performances of the Hop Up rubber?
