Alright, I ordered the AirsoftGI 6.01 TBB a couple of months ago because I was strapped for cash. For $35, It had to give me some sort of accuracy increase over the stock barrel which wouldn't even let me hit a soda can at 40ft 
So I go ahead and install the barrel ( the hop up is shimmed, bucking is seated correctly and cleaned) Then go to shoot it. At ~180ft the BB curves about 5ft to the right almost every time.
All I can think of is that It has to be the barrel. Any thoughts to why this is happening?
FYI: I am using washed KSC .30g BB's
Help would be HIGHLY appreciated
