Played around with my Nordic 18" upper; put it on a C3 lower with a RRA A2 Operator stock. Mounted a cheap 2-7x scout type scope on it. Will take it out next week to see how it does.
Thinking about removing the backup sights and freefloat rail and installing the under rail to where the PEPR is currently mounted and mount the PEPR on it. Hmmm
