Hello guys today.
I've got a short question. The RA-Tech rubber (blue) hop up I got when I bought second-hand my M4 seems to start to get tired, so I'm thinking of replacing it soon.
I've heard the stock rubber (black) is just as good. What you think ? Since I'm ordering a bunch of parts from KJ Works, I'm wondering if I should order it one too.
Thanks for your feedback !
