I put pictures in each folders so if you get confused about which one is which since I renamed it "Iron Sight 1" and so on. There is 7 in total, some which were REALLY hard to aim with since you couldn't see anything, so I editted it so you can actually aim, and yes, they are accurate. I couldn't make alot since only 1 person actually pitched in to help me to find pictures of iron sights.
Here are some of them, just rename the DTX files if you want it for different guns.

This is V2 its better.
I had to do a lot, and it was hardwork so thanks, and rep please, and don't forget to thanks and rep Zamaking too, he was the one who helped me with editing scope DTX files.
Inject the DTX files in UI_HUD_Info
Rename the DTX files to these file name for the following guns then inject
P90: SMG_SCOPE_P90_01
G36E: AR_SCOPE_G36_01
L85 MOD: AR_FOCUS_L85A1MOD
AUG: AR_SCOPE_AUG_01
iTech: DOTSIGHT_STYLE_B

Credits to me, Zamaking, and my testers!
OH BTW, THE DEFAULT DTX FILES IF YOU DO INJECT THEM ARE RED-DOT SCOPES, LOOK AT THE ABOVE TO CHANGE THE FILE NAME TO MAKE IT WORK FOR OTHER SCOPES/GUNS. YOU MUST HAVE A RED-DOT SCOPE OR THE OTHER GUN/S OR SCOPES TO USE IT, I CAN'T JUST MAGICALLY ADD IRONSIGHTS.
AS TO NOT MAKE SPAM IN THE MOD SECTION I WILL ADD NEW ONES IN THIS THREAD, HERE ARE THE NEW ADDITION, I WILL ADD A NEW ATTACHMENT FOR IT
