I play in low rates c4 server (x6 x6 x6 x7) and there lots of people tried this bug and said it works 100%. When you enchant your weapon to +4 it starts to glow.. If u look at weapon u can find that light goes brighter then dim and brighter again... So you got to enchant your wheapon when this light is brightest... But you can enchant like this till +13(i don't remember exactly) becouse the light goes too bright and you don't see when it's brightest... So what u need is a good reaction and scrols Try it and write if it works
