I have the MVP Varmint. They're a gimmick gun. If you don't have a particular need to have the >10rd mag capacity but be limited to STANAG mag length, then pick a different gun. The bedding block is plastic and cracks almost as soon as you buy it. The bores are like 5 miles of carpet bombed dirt road. The chambers are a hot-dog-in-a-hallway kind of situation and the factory wood stocks are never straight. Also, twist off the factory scope bases right away, they bent/broke on my gun the first time I did a barricade match with it and there's a lake of oil under them from the factory.
In my pursuits of getting mine to shoot right I replaced the barrel, scope mounts, recoil lug, trigger, extractor (4 times until I got an aftermarket unit) & detent ball, and stock. Now it has a Columbia River Arms 26" 7 twist barrel and the only things on the rifle that came with it is the receiver and the bolt (minus extractors which I've had to replace 4 times).
If you like to shoot high volume varmints then it's fun but still has too long a throat to do really well with varmint bullets.
