He can name the thread whatever he wants
It's HIS thread
About the mod:
I had trouble finding the scope as well.
I was modding the Tgp-1 pro. And i didn't want that crappy design on it so i just modded the Tpg-1 Master scope and renamed it to the Pro scope and Re-injected it.
They are in the Texture folder for Sniper rifles. Just look for it.
But i don't really like the texture
But I hope i helped
