I agree. Just about anything on full auto is hard to control. I will say that an H&K MP5 is an exception to that rule. You can put a three round burst center mass just about every time at 25 feet. Combine that rifle with a holographic reticle scope and it becomes a surgical tool as far as accuracy.Well, I also dinged the bullseye regularly at 500 yards. I'm thinking the AK-47 wasn't so well known for that. However, I've never trained on an AK, so I don't have a basis for comparison. And the M-16 has been replaced in any event.
I frankly have doubts about being able to keep the target sighted with any handheld automatic weapon while it's firing on full auto.
