That is what I was thinking, but haven't held the new keymods. Do you know if they keep balanced with the heavy barrel? My issues with the old quad rail was how front heavy it was, totally ruined it for me ( I really can't stand it ).
In slow fire it shoots as well as the heavy barrel, but it does heat up and the groups open up much faster. If you're doing lots of running and gunning, I'd suggest the heavy barrel. For lugging around coyote/deer hunting, the light barrel sheds a fair amount of weight without loosing out on accuracy for the first few shots.

Don't own one but have shot lots of them.
