/me wonders what books Conglomera got his info from.
Pistol's, where is the Browning HP?
SMG's I'd expect to see AKR type weapons, Sterling SMG, Uzi, M3 Grease Gun (very popular in its time and still found in the 3rd world).
Rifles's let try FN FAL (probably the most popular battle rifle ever), L85 (ok I'm biased), M14.
MGs I'd expect to see the RPK and FN MAG in this list at the very least.
But as always weapon suggestions are generally ignored. Now if you want to model them and approach the team to see if your model is of a high enough standard to be included.....then suggest away
