I don't know what I was expecting but I was expecting something a little more potent (no I wasn't expecting the best weapon I have ever used or wishing that it would be overpowered}
I wouldn't go as far as to say its a bad gun but its more a pointless addition. Thinking about the weapon over the 3 ranges: long, medium and short. the weapon is poorer than others in its own class and other classes.
Long Range - This weapon has a strange kick pattern which makes it very difficult to control. Both the Remington and the AK would be a much better AR at this range. Even with grip and flash suppressor I find the weapon very hard to control at long ranges.
Medium Range - Even at this range the weapon isn't very strong, both the Honey Badger and the AK are far stronger with less kick.
Close Range - Oddly this weapon is probably best at close range, at very close range the Maverick can kill someone in 2 bullets no problem. But even at close range I would rather go for something like the MTAR or Vector due to the fact that the Maverick has a very slow fire rate and the mobility isn't great.
All in all I am a little disappointed. The Peacekeeper was a decent addition to BO2 but the Maverick just feels like a bit of a nothing addition to the game.
