i too wondered whether the carbon fiber was a just gimmick or worse a insulator thst would do more harm than good. Seems it would hold the heat in and keep the barrel hot longer.
Although I'm not an engineer either, it's my understanding that the increased surface area and the type of material used to wrap the thin steel barrel actually promotes cooling as opposed to heat retention.
I have not had any problems with shifting POI with my rifle, although I shoot short strings of 3-5 shots. It's a hunting rifle.
