what i read said the burst trigger group was a lot more prone to failure than the auto trigger group. they also sited that with proper training a full auto works jus as well as burst (trigger discipline)

i'm trying to remember where I read that but I can't remember.. it was a military news site of some sort...

it's possible that they said they are looking into going back to full auto, but haven't done it yet or it got shot down (sort of speak ehhe)
