I'm curious about the brass nose cap and other items on my Mosin 91/30. Looking on 7.62x54r.net, their pictures don't show brass or mention it at all. Is this an odd variation or something? I have brass on the nose cap, and on each end of the handguard on top of the barrel (right after the rear sight, and right before the front sight, on top of the rifle). You can kinda see it in the pic below. Anyone know if this is standard? Did I get something different/interesting/rare..?
