Darn good discussion, never shot a CRF yet, but if'n it works as good as stated and could be added for little I would be for it. I'm guessing, the Axis and Stevens would have to do without, thus:
1) Would have to make and stock two type of parts.
2) on the plus side, could be a bonus for those paying the extra for the upper level rifles. (prices are creeping ever closer to big guys)
