Have some of the earlier concerns expressed over the bolts head design with the drop down split head feature.
In this review there were other concerns on feeding reliability and weight of bolt lift

The AR-15 magazine was designed to sit much lower in the receiver than normal hunting rifles, and so the next cartridge coming off the magazine is a little bit too low for a normal style bolt to pick up. Mossberg’s solution to this problem wass to design a bolt with a lower half that splits open and a lower section that digs down into the magazine to grab that next round.
The impact of having a magazine that sits that low is no bueno for reliability. I had more than a few instances where the round ended up off center and the bolt failed to chamber the round on the first try. I get the feeling this is due to the spring in the mag “popping” the round up as it leaves the feed lips, causing the round to lodge slightly sideways rather than feeding smoothly into the chamber. http://www.thetruthaboutguns.com/2012/09...sberg-mvp/
The bolt itself looks great at first glance — the handle feels nice and grippy and it looks very pretty — but once in action, it’s not as pleasant as it would seem. It takes more force to get the bolt open than I’d like, requiring a firm grip on the bolt handle to crack the thing open rather than giving me the ability to simply use the side of my hand as I prefer. That’s not to say it’s terrible, just very heavy for such a light and small caliber.

I do think the ability to use different magazine capacity for different applications should be a bonus but wondered if other real world usage had bourne out the reported doubts I origonally saw expressed?
