Ripp,

Thanks for posting. That is an interesting, takedown rifle.

It seems that a number of speciality rifles use barrel extensions with replaceable bolt heads which allows light weight. unstressed actions and quick barrel changes.

I am not sure why they selected 20" barrels for the high power cartridges listed. Any thoughts?

Are the barrels carbon fiber wrapped which many high end manufacturers are using to lower weight and improve accuracy by stiffening the barrel? If so, I missed that.
