The Mossberg MVP I ordered through a local shop came in last week. I picked it up and took it to the range yesterday. I put the only scope I had available on it - a cheap, 3X9 Tasco. It produced a 1" group with Fusion 62 grain ammo that a buddy had (and he shot the group).
Best I could do was a little less than that with 193 and PMC 55 grain.
The good:
Rifle looks nice (see the photo). It's light and points nicely. It shot and ejected everything, including some Tula steel. Free-floated barrel. A variety of AR-15 magazines worked, the best being the supplied 10 rounder from Mossberg, which will fit into my ARs fine. Pmags took a mighty thump on the bottom to make them seat, though. Metal mags seem to work better with this gun.
The bad:
The bolt takes some effort to open. You'll have to take it down from your shoulder to load another round. Maybe it'll loosen up but I doubt it. Couple of times the bolt slid over the magazine without stripping a round - you'll notice this because less effort is required than when it picks up a round.
And my main complaint, although I knew this when I ordered it - no iron sights. I think every rifle ought to have them and I am willing to pay for them.
The ugly:
None to report - the rifle looks nice and handles well. My buddy said, "Hey, a mini scout rifle!" Yeah, right, except for no iron sights!
I'm going to keep it and get a decent scope on it. I might even price having some irons put on it by some local gunsmiths.
