The BETA m16 iron sight
 

I guess that Baldo already seen this :P (attached image or here)

If not, try to do it, the beta-style is alot better than the final game.
How they can change that? Also they removed the fantastic sniper scope effect ... only with NVG on you can see it.

How about these, from my RelapseMG mod:

Nice one

Hey will you publish the Relapse MG mod?

Eventually, yes, I have every intention to.
