you mean that you can't zoom while on sniper? Try using "Z" from your keyboard or Middle mouse button if it not working you should check your setting of keys.
Set the default setting if u dont know how to do that.
If it is still not working then you should download another scope mod.
Hello my friend. A-Team Roleplay will be back soon, you should read the thread made by David. I can not tell you the exact that when it will come back but i am sure it will come back with a great update, which had never been seen before by someone.
