Whoa, new quoteboxes(?) are melting my brain. Played single player and have fired the M16A4... as far as I can remember it's full auto, not three round burst.
I bought WaW when it went on sale for like $30 but never really played it. I think I only played the demo online, sadly. I do recall Gewehr from the original CoD, and I didn't like it. My CoD heritage is all about playing the large open United Offensive expansion maps and rocking open sight mosin nagant or kar98k. M16A2 was as close to that feel as I could get in CoD4... Right now I'm using the SCAR-H or whatever.
I suppose I'll go check out gamefaqs and see if someone has good comparison charts for both of the games, maybe FAMAS will do the trick and I just need to get my CoD legs back. Charting out the characters and vehicles for Mario Kart Wii did wonders for me online![]()
Saw a rating chart-the FAMAS is weak w/out silencer, weaker still with. The Fal? Most powerful gun in the game.

FAL = 50
Famas=30(There are stronger pistols).
