I bought a predator 18.5 inch 5.56 MVP the day I seen one advertised. Quite reliable, people ##### about the bolt mechanism, but I have never had an issue or heard of anyone with one having problems.
Point of fact, although this is the least expensive rifle I own, it is also the most accurate by far. I got an honest to goodness 4 shot group at 100 yards that measured .34". Most of the time it is an honest .5-.75" shooter...with most quality ammo. I have had very accurate rifles before, but they were picky about what I fed them.
These are solid rifles other than the finish on the metal. It is delicate, and does pick up rust relatively easily. In fact, I just cleaned up a Mossberg for a friend that had rusted in his cabinet over the winter. His fault for not oiling it before storage, however it was worse that I have seen out of rifles with a quality bluing.
