bottom line

[tippmann111]

My friend has a bushmaster and it came with no bottom line. He bought with it a 90* pice to put into the asa were you screw in the pice and then some macro line. He tried to put it on but would not fit into the reg. fitting or asa fitting. any solutions? how did you guys install the bottom line on your 2K bushmaster and what did you use?

Did you friend buy a Macro Line Kit? Because if he did he needs to screw one of the 2 fittings in the regulator and the other in the bottom line piece the screw the bottom line piece in the bottom of the grip frame with 2 screws

lastly get out one of the 3 hoses that the kit came with and connect the 2 fittings with the hose.
