I already have a Deadly Winds Fibur X 14 inch on it (yet to test it) and I was trying to think up any other ways to make it more quiet. I was thinking if I improved the efficiency and lower the FPS a bit it would help quiet it down because less air less noise right? I haven't seen very many bolt options to quiet it down, any ideas for that? I have also heard of different spring combinations helping to make it more efficient and or quieter? Currently I have the lightest main spring on (Blue >15) and have no clue what my valve spring is..
Any ideas or discussions on making it quieter are greatly appreciated.
P.S. I've already looked into rain covers so no need to suggest them
