Can i use the iron sights on guns like the m16 on battlefield bad company 2?

Somebody told me that i cannot use the iron sights on a gun in battlefield bad company 2 only the acog and the red dot. Is that true? Please answer.|||Yes you can use the iron sights on the m16. You can use Iron sights for every single gun in the game, except for shotguns. Whoever told you that was misinformed completely.|||Yes you can thats what the original guns come with but you can unlock red dot and acog by using those kits frequently.|||shouldn't this b posted in gaming??? this is the real life hunting section not video games.....|||To answer your question - maybe. check in the gaming section.
