Obviously its the ump45 or ak47 both silenced, with claymore, and flashbang, with the perks, obviously one man army pro (which is your secondary) also cold blooded pro, and sit rep pro, or commando pro.
and these are the guns i get my nukes with my first was with ump and always with it then the ak47
You need the warlord perk.
use the perk warlord
Go to your perks and go to War Lord perk and select that then you may buy and put on attachments on your gun. :)
You can have both attachments on if you unlock the gun perk that lets you have two. ie, kick, focus, attachments
In Call of Duty 4 each gun could only have one perk on at a time.
Use the Warlord perk.
The best mw3 gun is the L118A but that's because I like sniping.Or if you put the first one on perk 2 its the best quickscoping gun
Yes, use the warlord perk (two gun attachments on the primary weapon).
only if you have a perk called bling. It lets u have 2 attachments on your secondary or primary gun
you go onto the class of the gun you want multiple attachments for the you go down to perk 2 and you should see warlord there you have to buy it if you haven't already.
by click the sertain perk and it will help u automaticly
use the perk 'warlord' or 'warlord pro' to get multiple attachments.
