Ranger Bob, your M4's and M16's are pretty good. A few minor issues:
1. The m4 has full auto, but not the m16. Nice sounds though.
2. Not many soldiers have death wishes. Therefore, they don't tape mags together with bright YELLOW tape.
The stock of the weapon is quite nice and beats FLiPer by a bundle, but I still prefer Koepke's m4, it is the best model of anything in OFP. Hate the scope glass texture though.

Here is a pic of an RPK-47, it is very nice.
