US NGSW 6.8mm by Cobalt and MARS

I didn't mean barrel life in the sense that they couldn't incur/afford the cost of replacing barrels but more that it seemed to me that it would be a pain to have to have the rifles go back for what I assume is depot level maintenance (for barrel swaps) so frequently.

I don't know about the US Army soldiers, but Canadian soldiers are lucky to fire 50 live rounds a year so barrel life is not really an issue unless they are in a combat situation.
 
Looks like SIG, Textron and GD are down selected again just a couple days ago for the NGSW ( not the old next generation SAW ).

Case telescopic ammo ( Textron-HK-Olin ) vs plastic cased cartridge ( GD-OTS ) vs brass cased steel base cartridge ( SIG ) - FN is no where to be seen at the end.

I like the Textron solution for the LMG/SAW, but all their carbines look like boat anchors.
