Fitting a HK93 stock to an MP5. What do I need to know?

Hey all,

I am wanting to make my AP5SD a proper clone of the MKE MP5 MTS A2( Their version of the MP5SD) and from the pictures I have seen they are running a metal capped HK93/53/33 style stock. Is it as easy as removing the 2 screws that hold the metal plate in, compressing the buffer, driving the roll pin out and jettisoning the buffer? Just want to get some input before I destroy something. Thank you in advance!
