The reference to modding a Systema Hopup unit refers to filing/rounding the front of the feed tube so that it fit the body. There's pics somewhere...I've saw them about a half year ago. But essentially you test fit it and remove the metal from the hopup unit that interferes with the body.
I did one a little while back...it works fine and not hard to do.
Or....contact Mach1 and ask Shinobii for a stock spare replacement unit.
I'd be tempted to try with the Madbull one...since it looks very similar (the dial on the ICS one is pretty big...so there might not be clearance issues with the Madbull one...you'd probably still have to mod the front of the feed tube though).
Nothing ventured, nothing gained (but often money saved
)
I'll see if I can't dig up the pics

*edit*
Not the same old pics...but similar pics are in the texas airsoft page
