Just got a RR the other day.

Feeds fine out of G.I. Mags but unloading them manually is a chore unless you mod the front edge of the mag.

Recoil from a 7lb rifle is interesting, especially for an AR platform. Not unpleasant or painfull, just kind of "Odd" if you have been shooting 5.56 for many years in an AR.

I like the one I have.
