Rex Posted April 16, 2017 Share Posted April 16, 2017 I'm looking for an ICS M4/16 upper gearbox shell and an ICS M4 hop up. I would prefer the metal version of the hop up but I'm interested in the polymer as well. Link to comment Share on other sites More sharing options...
Darth Posted April 16, 2017 Share Posted April 16, 2017 I think I have an ics gearbox. I'll look Monday when I get home. Link to comment Share on other sites More sharing options...
Rex Posted April 20, 2017 Author Share Posted April 20, 2017 ICS Upper shell found. However, I'm still looking for a metal ICS M4 hop up. Link to comment Share on other sites More sharing options...
