7.62*39 reciever (i love russian stuff but 7.62*39 in an m4 is just wrong), run it with rpk mags
stubbiest barrel you can get your hands on
and the stubby version of the full stock
add in some stupid coloured reciever parts (purple and orange would be a good horrible combination), magwell grip and for the pistol grip get the most over-specced dmr/sniper grip you can find.
scope wise i suggest a stupidly overpowered optic, preferably one long enough to extend further than the barrel.
then sit back, admire your handiwork, and realise we're both going to burn in hell for the abomination unto god we've just crafted.
