wow, just the work in making an airsoft MK19 even work, and then the cost of the shells to actually operate....wow, just wow....cool but that would be expensive.
Oh on a side note, In OIF1, when I crossed the border...I only had a M249 as a vehicle mounted weapon.....our MK19's weren't in counrty yet and the ARMY, didn't see the 50 cal. as a reliable weapon til after we passed Baghdad.....
