:EDIT: VIDEO COMING SHORTLY!
One, I can't post video, sorry.
And I can do pics if you'd like... but it would just be me taking pictures of my TV screen.
Two, it does work, but you aren't going to see your grip on your gun.
You'll notice how your first slot will say attachment.
Third, it won't work with anything other than Shotty or LMG... and to be honest I haven't tried it on the SAW, so I can't confirm that.
Don't post saying how I'm a retard, when you in fact are the retard who can't do it.
Read the tutorial, it's spelled out in there.
If you think it's fake, I don't care.. I'll be the one pwning with my sight and grip
