Element JG-style RIS install on G&G GR16
 

So I bought an Element JG-style RIS from Frank and his crew, however there's some kind of fandangled mounting bracket for the RIS that's different from the mounting system for a standard M4 handguard. The bracket interferes with the outer barrel, and doesn't reach the delta ring. For the life of me I can't figure out how to get this bastard on there, so I'm calling for help!

If anyone can help, I'll really appreciate it!
