Sup i found this glitch and it works ok so this is how u do it.
-Ok so i m buying Scope Which is locked!!!
-Go to modification with ur regular gun or with any gun who got no scope..
-Click on regular Scope and click on buy then it says Prices click for 1 day then "OK"
-Now it says Attack or Cancel Click on Attach and as soon as u click on Attach click on the one which r locked and i clicked on the last one which was LOCKED.like if u wanna buy Scope then buy regular Scope and then click on the 1 which is locked, same in supressor....
Look at my Lvl and look how i unlocked the Scope

boomber you need to click have a gun that do not have a compressor or a scope thing then when you go on says Mod you wil be able to do it just click at a Scope thing called ACOG TA3 Scop when you click it to buy it..its going to ask you if you want to attach it you will need to click "Enter" and as soon as you click enter and double click really fast on a "Compressor or a Scope" you want to buy
