Just got this rifle this afternoon. Overall the fit and finish of the rifle is surprisingly good. This is my first Mossberg rifle. I've always been interested in the MVP (Mossberg Varmint Predator) rifles since they came out back in 2011. This one has the Flex exchangeable stock system on it. It came standard with a M4 style collapsible stock, and A2 pistol grip. The barrel is a medium bull barrel with flutes. No muzzle device on this gun, which isn't a big deal. 18.5" in length, 1/9 twist rate which is just fine for the 50-69 grain bullets I like to shoot. I decided to top the rifle off with a Vortex Crossfire II 4-12x44 scope.
I zeroed the scope at 50 yards using XM193 5.56 ammo. My three shot groups are just under .5" which is better than I though I'd get with the ammo. The gun also works with PMAGS. But the follower is a little too tall when the magazine is empty so the bolt won't close. No issues with the steel G.I. magazines though. So that's great news!
Overall I'm happy with the rifle. Should be a nice shooter.
