Has anyone expended the effort to modify a free float handguard (ie, Centurion or ALG are my go-to) by cutting back the front or cutting out a space from the top for a FSB? Additionally, would there be concerns about the structural integrity of the handguard afterward?

I thought I’d seen this done by someone before. I understand it is not necessary. However, I really like FSB’s and would like to utilize them with longer slim, free float MLOK/Keymod handguards.
