Ok two water cooled M-16's using beta mags. First why would you be messing with a dual M-16 set up as a spec ops unit? Why not mount two SAW's or M240s on that mount? Belt feed, made to fire a lot of rounds in a short amount of time. Either are much more realiable for high rates of fire for long amounts of time. But, we are going to go old school and use water cooling on this set up even in the 40's things were going aircooled. Oh and I have never seen a guy in the military even the Navy have a uniform as ATE THE HELL UP as that so called LT on the show. Wrinkled, no name tags, buttons unbuttoned, ect....... Anyways why not use one right handed upper and one left handed upper? That way all the brass is flying out away from the operator and his sight line? Where are all these OPERATORS coming from on this show?
