Lifetime Weapon + AWM Code = screwed?

Hi,

Just confirming, I have a lifetime barret on the 3rd slot of my sniper and I want to buy an AWM retail code to add on. Will the the gun be in my 8th slot and will the barret be removed or will they both stay and I can use them both in game?

Thanks

use an extra slot hack. it will add both i think

The lifetime weapon will stay. Just don't mess with the 3rd slot and nothing bad will happen to it.
