If you're trying to convert a rivet pattern FSB to screw pattern, then no; the existing hole is too large for the SKS screw. I haven't tried it on a legitatment screw FSB.

You will more than likely need to turn the barrel down slightly behind the original FSB on the MAK kit since it wasn't originally meant for the longer spiker FSB. Other than that, it should be a straight forward swap.
