Just bought my first Aeg
hey i just bought my first AEG and its looks great the guy at the store said that i should downgrade the original spring due to me playing CQB style all the time and that there was one in the box for me to do that. After i left the store the downgrade spring have a tag that says its for 400fps now i'm just not sure if that spring is going to be downgrade or not. If not could you tell me the specs of the spring to get it down to about 350fps or so please.
P.S: i saw the spring charts and that rly means nothing to me because I'm new to airsoft and no clue what it all means well for the most part.
