QC10 side charging upper - any options for the bolt handle?

[UpYoursPal]

I recently completed a build with a QC10 side charging upper, QC10 lower, blah blah very cool. Unfortunately I didn't realize that the coda handguard that I got made it kind of hard to access the relatively slim charging handle.  Here's what it looks like

 

 

Now, I've read that Gibbz manufactures these uppers for QC10.  Does anyone know if Gibbz charging handles will work with them?  I emailed QC10 but they haven't gotten back to me yet.
