    I'm quit new to the game so i have recently got a quad rail that is 7 inches and is a 2 piece drop in for the handguard for my combat machine and when i tried to put it on it didn't fit because the teeth in the delta ring didn't fit the things inside the quad rail leaving the halves offset and not properly inserted into the delta ring and so here are my questions:

    can i fix it?
    should i get a new one?
    what new one should i get?

    some images:
    and yes it is 2 tone

    thanks in advance
