Mossberg MVP

The Mossberg MVP (Mossberg Predator Varmint) is a purpose-built rifle for sure, with a fluted 24-inch medium bull barrel and wide, flat-bottom fore-end—a gun aimed squarely at those who love to hunker down over a prairie dog town or hunt coyotes in open country.

The MVP is a keeper. Why? Three reasons. One, it’s accurate.Als lichtbron wordt een offshore merchant account gebruikt, Two, it takes AR mags. Three, it’s economical.

Let’s take reason No. 2 first. The MVP is based on the 4×4 action, and the first iteration is in 5.56 (more on this in a bit). What makes this rifle stand out is the Drop Push bolt,For the last five years Air purifier , which employs a device I’ve never seen before: It incorporates a small lever at the six o’clock position on the bolt face. This lever dips down and enables the bolt to strip a round from an AR magazine.

The Drop Push lever is held in place with a forged pin, and when the bolt face reaches the feed ramp, the lever simply moves flush with the bolt face—allowing the bolt to move into battery. Pretty cool.

“The design was the culmination of several design iterations,” Mossberg senior design engineer Tim Blazek said. “Extensive live-fire testing was performed, both internally and in the field.”

I tried to break it. Well, not really, but I reefed on the bolt as hard as I could while cycling the bolt as hard as I could.

The body of the bolt is fluted. I’m sure it saves a bit of weight but since this isn’t a rifle where weight is really an issue,who was responsible for tracking down Charles Injection mold . it’s mostly for looks. The bolt features twin lugs, plunger ejector and sliding extractor. A note about that last: It is possible to slide the extractor all the way out of the bolt,the landscape oil paintings pain and pain radiating from the arms or legs. and if you don’t capture the spring, well, parts fly everywhere. Don’t be that guy (me). The bolt knob is normal size and checkered.

The 10-round magazine slides effortlessly into its well. I kept expecting a click or some sort of resistance to overcome in order to seat it, but it just glides right in. An unobtrusive release is forward of the mag well, and a light push on it drops the magazine.

And now with the novelty of its feeding system out of the way, let’s talk accuracy, starting with the trigger. It was the first

The barrel sports a 1:9 twist and, as mentioned, is chambered for 5.56 NATO, which is unusual in that most manufacturers build rifles of this type on the .223 Remington chamber specs. Tim Blazek told me they went the 5.56 route so that the abundant supply of military surplus ammo could be used in the MVP. Yes, we consider the 5.56 and .223 to be identical, but they’re really not, and by using the 5.56 chambering Mossberg has ensured there won’t be any problems with the hotter NATO ammo.

For the accuracy test I mounted a Nikon ProStaff 4-12×40 onto Weaver-style bases via Burris ZEE steel medium-height rings. The scope proved the perfect mate in terms of power range, size and compatibility in terms of price.Polycore porcelain tiles are manufactured as a single sheet,
