Oh no don't worry, I just didn't realized than this is UK forum. Actually i am from Slovakia and there are no limits for the AEGs .
About the battery: i am using 11,1V 3S Li-pol battery with Perun mosfet but i am going to change it for Jeffron leviathan V2 processor unit.
So i would like to keep that spring in for now, in our country most of sites have 400FPS limit for AR's so i am fitting quite well. Is it still okay to buy 1:16 with that spring or i should stay with 1:18.
Thanks for your answer and have a great day. 🙂
