This is a sniper scope replacement for all snipers (including the off-center Dragonuv scope). This does not change the thermal scope, but if you want it to, post a request.
This file was only tested on Windows 7 Ultimate SP1.
Instructions:
Open up "iw_04.iwd" (in your MW3's "main" folder) with WinRAR or a similar program.
In WinRAR, double-click the "images" folder.
Drag both .iwi files (from my pack) into WinRAR and click "Ok".
Wait for the archive to update.
You're done!
