Hop up rubber/bucking help
So it was recommended i should upgrade my JG m16s hop up rubber bucking. But i see alot of different choices for these parts. I also plan on picking up a promethues tightbore barrel aswell. But im not entirely sure of which one would be best for me. Right now im looking on ebay at the :
Lonex - Improved hopup bucking 70* Rubber
G&G Cold resistant hopup
Madbull - 60* Shark Blue
Madbul - 60* Shark Blue Normal
Madbull - 60* Shark Accelerator Red
Sorry im a noob.
