Don't worry, it won't get dirty or fog up. I'm sure getting a proper cheek weld will be no problem. Those tubes running down your head to your back will never get snagged on anything, whipping your head back suddenly. Slinging your rifle over your shoulder or back absolutely won't yank all that shit off. Signing for a bunch of SI and spending hours PMCS'ing it and standing in line to return it isn't an issue. All the batteries being dead because the last guy didn't turn it off will never be a thing and the pelican case you have to store it in will easily fit in your ruck - you won't even notice it.

And for all of that convenience you'll receive: slightly less combat efficiency. Please sign here to buy a million.
