I've read and heard a lot of talk about the HK M27 IAR being examined as a possible replacement...not for the M4, but the SAW. I'm confused by this. Yes it has some nice features being piston driven with an adjustable gas system, it's proven to be very accurate in full-auto, and it's obviously lighter, but how can it really replace a belt fed?
