So I'm not going to go into detail about how I acquired a TM AK47. But what I'm concerned about it how well it will take a spring that shoots around lets say 350-370, or what about a spring that shoots at 330-350? The gun as of now shoots at about 250-270fps, which is just too low for me. (And for anybody to even feel a bb.)
(It HAS been reccomended that I do not to open the gearbox unless I want all the little fairys to fly out and make the gun less accurate. And I DO NOT want to cause harm to anybody or anything by increasing fps, I just want people to feel the impact of the bb, etc.)
