Mw2 - Mounted Machine Gun Glitch

Hello everyone, this is a glitch involving the riot shield and the mounted machine gun. For this too work you will need a riot shield and a mounted machine gun (Obviously). You will also need the one man army perk which is unlocked at level 45. If you follow these simple steps it should work fine. If you have any questions PM the channel and we'll try to get back to you as soon as possible. P.S Sorry if i am a bit hard to hear my mic is messed up next video i will either use my PSN mic or try to get my friend to record instead.
