First of all I think your build is absolutely fantastic so I hope you won't mind this observation which I don't want you to take an criticism. I was just looking at the screen cap you posted and your build and I noticed something. Is it just me or does the ammo belts in the screen cap look thinner and wider than the one on your build? I only ask because you were striving for such accuracy and your weapon looks so amazing regardless.
Cheers.
Markus, I've no idea how to display something so big. I'm going to sell it in the new year.
TymerDC, I think you're right. My ammo belts aren't big enough for a 50cal round.
Wes R, I think you may be right. Seems more than a coincidence.
