I didn't realize they had decided on a design yet for this role so I thought you guys were talking about the LWRC M6A4 which is closed semi and open full. USMC chose the 416 variant instead of the LWRC. I think the closed/open config is an awesome system myself but I have not shot one. I have shot the regular 416 and it is a nice rolling m16. Sorry for adding confusion.
I love the SAW and I don't care if it weighs 40% more or whatever or draws more attention or whatever else people say if I was going into a situation that needed suppressive fire like that I would pick the SAW all day long. If you ever get the chance to shoot a SAW and havent you need to do it. Loads more fun than a M16. here is a pic of me with a saw just to show my love of them.
