That clip is to take the play out of various lengths of lower forends so technically no. But I would suggest working it so you can keep it like it should be. Is the lower handguard flush with the receiver? If not start there. Then if necessary Dremel the front part enough to get it to lock in place.
The rear is flush, I dremelled the front a tiny. I took out the clip and bent it down a little so it would compress easier. I think I will just roll with it like it is till it gets loose then try a fix.
