Im wondering what the difference is between TM's and SCR's M4 are, i hear the parts are interchangeable. A Few Questions.

1) Can You take apart the src m4 the same way as the TM?
2) If i get the m4 metal body, do i have to get TM's Parts?
3) There Appears to be no spring on the cocking lever, but ive seen other TM M4s that have the leaver spring back, can i put a spring into mine?
4) How do i Dissassemble the SRC RIS?
5) Side Sling Mount, better than lower mount? or not?

Any Answers to these questions would be much appreciated

cheers,
