With the long barrel attachment, I'd say its on par with MW's SPAS-12, maybe a little more, but there is no slight of hand, and the fast mag attachment doesn't speed up your pump action so if you run into more than 1 person, you might take them both, 3 you'll die. It's the most handy camper killer in the game.
The game has its issues, like the 1 sniper rifle that you can shoot as fast as a m4 with zero recoil, but it's worth red boxing Strider. Black Ops 1 was pretty good, MW3 was so bad, I wouldn't be playing this game if I didn't get it as a gift. It seems Treyarch makes a better COD now. I'm having a bit of fun. I rarely get kill streaks but I still pull off matches like 23-9, 15-3, etc. in fact there are hardly ever any score streaks spamming the map, unless you play demolition. They set the lowest to the equivalent of 4 kills, and you only get 25 points for score streak kills, so it's really difficult if not impossible for one to lead to another without more kills.
