I have a MR in .22mag. Mine has been very accurate with 30gr Vmax and Rem 33gr Vmax.

The trigger is horrible, but I haven't replaced mine yet.

Mine will shoot roughly 1" at 100yds with Rem 33gr's.

I had my weaver rails opened up to picatanny to accommodate my NV. I also had my receiver coated in graphic black cerakote and had my bolt bead blasted.

Only thing I'm not too crazy about the MR is the integra sight rail sits a little high and the lack of comb on the stock doesn't help the situation.
