If it was Future Weapons, thats like saying Horsepower TV gives accurate information.
I love being able to absolutely destroy something with a rifle, not just poke a bunch of holes in it. I wish we had taken pics of the bug - the engine block was litterally shattered after just a few rounds. Against flesh - uhm, lets just say that the hogs I've shot so far with it weren't in any condition to be photographed. It wasn't pretty
It's a bitch to shoot though, you are pushing a huge round (334g or larger) and that energy has gotta go somewhere. The AR action can only take some of the sting out. It's got a really sharp kick that will beat your ass if you don't have good shooting form. The first day I shot it I put 20 rounds through and had shoulder problems for a month and thought about selling it. Only after talking with one of the guys at AA did I learn that I was trying to pussy foot around like a virgin teenager with his first time - not the monster dicked porn star with the hot new starlet. After that it became a lot easier.
Biggest problem is ammo availability. You cannot find commercial ammo easily. Cabelas used to be pretty good about having a few boxes on hand, but that's dried up and they have stopped carrying it as I know. I have a friend who lets me use his reloading setup and my dies, but the brass is also running short. I've reuse brass, but I don't like constantly recycling no matter how good it looks - gotta have fresh stock from time to time.
Until AA fixes their ammo supply issues, I'd hold off on dropping any change on it - sucks to have a rifle that you can't shoot.
But when you shoot - oh baby.
