Clean the barrels and buckings, your KM16 bucking may be a bit greasy so your not getting good hop on your shots causing them to fall short.
I cleaned then very well. I'm talking about consistency and grouping of the shots. My M4's grouping is tight at that distance. The KM16 is like everywhere.

At 70ft it's really not going to make a difference on the length of your barrel. I can take my km4 cqb with my 285mm prometheus and the accuracy will probably be the same as your m4. Now if you go to about 100-150ft then you will see the difference. In your case since you are using the same barrel in both guns it could be the weight of your bbs. If your using .2g for your regular km4 carbine with an m120 spring and you use .2g for you km16 with an m130 spring your km16 regardles of barrel length will be less accurate, because the bb is too light for the amount of fps. It's all about ballistics, but I can't really go too in depth with the calculations, because I barely know them. Now if your using .25g or .28g bbs in both guns your km16 will be more accurate at longer ranges, but at closer ranges, both guns will be as accurate as each other in theory. It could also be the position of your hop up nub. Your km4 carbine's nub is probably aligned almost perfectly at a 90% angle and your km16's nub is probably alittle off causing an inconsistent backspin on each bb.
Sorry I forgot to mention I was using .25's and they have different TB's. JBU on the M4 and Prometheus on the KM16. I will try looking at the nub and see if it'll make a difference.
Going back to the topic of this thread, I suppose the improvement or difference made on the KM16 over the KM4 series are the spring and the piston as mentioned by one of our forum posters earlier.
