My LRH which is the most current configuration does not have a fluted barrel or the wedge configuration in the accu stock. Only an aluminum bock, which I prefer. It does have a heavier barrel than the FCNS. It is in 6,5x 284 and consistantly shoots .25-.5MOA at 500 yards. Only have to sand a little off the fore end tip where there was some barrel contact. Overall I am very happy with this rifle.
