sp-1 carrier

[lx2008]

hi guys, new here but i`ve been reading a lot of the posts and i think i may have made a big mistake. my RLL should be here in a couple of months(i hope!) but after doing some reading i thought my ar15 carrier was sp1 style but is not. according to you guys this will not work with a RLL. (POSSIBLE KABOOM!) where can i purchase an sp1 style carrier? hope i`m not SOL. thanks.
