David Crane of Defense Review has an outstanding write up of the next gen magazine for the Infantry Automatic Rifle.
This is a must have if this system is going to work. I'm still not convinced and STILL believe that this is a boutique purchase to satisfy a small segment of Marine Corps leadership.
The Gunners are getting their way.
PS.
First. The drop test that they performed was silly. If it works then we'll know when its tested out at 29 Palms with the boys from the 7th Marine Regiment.
Second. I can tell you what's going to happen operationally with this weapon once it hits the fleet. Officer, SNCO's and Squad leaders are going to scoop them up and take the tracer rounds from their boys. They're going to use this to mark targets for their Marines or as a way for them to apply suppressive fire themselves at targets of opportunity. I guarantee SAWs will still be humped and this will be used in ways that are not being thought of at Headquarters Marine Corps.
