When I was in Afghanistan, the weapons techs were showing me an AR10 they were repairing. It had both a night vision scope in line with an optical scope, and was well used. They were the companion rifle for the bolt action snipers. The weapons techs told me the companion rifles actually were getting more kills than the bolt action.
As to the price, figure it is likely about half that, with the other half being service spares and support.
