Magpul XT rail panels

Bought these during a shopping spree at firearms outlet Canada but got home and remembered that my handguard is mlok, and not picatinny (idiot.) I opened the one rail before I realized how dumb that was so one package is open but I have 3 rails and the other 2 are still sealed. Never been set up on a gun just been collecting dust maybe somebody can dress up their rifle!
