Ics M4 with madbull ultimate hopup

[windwalker]

hi there sorry if this has been asked before ..........

I have filed down the unit and it sits nicely in the ics m4 and the tracer is working well. I have found that the part of the hop that mates with the magazine is about 1.5mm shorter than the standard ics hopup and i have to push the mag into the magwell for it to seat properly.

I was thinking of trying a systema hopup but not sure if it would have the same problem

I also noticed that the bar across the lower reciever in the magwell that hides the wiring could be dremmeld down a bit to let the mag sit higher?

any help would be great......

ICS are a bit of a pig for after market parts both internal and external. I would have stayed with the sock unit as it is very good and will work much better.
