I feel to make the gun authentic it needs that scratch though I would prefer it to be as light as possible, unless of course you're lucky enough to get a new one that was either never issued or issued and never taken out of the box or just stuck in a drawer until the war ended.
I thought about renaming it?
1. Why is the drill Sargent yelling at me while I'm trying to field strip my weapon....scratch?
2. Why are they shooting at me can't they see I'm trying to clean my weapon....scratch?
3. (My favorite) oops these things are really tight when their new....scratch!
