I spent a whole day playing outdoors with one just recently.......well, a few months ago.
Had it setup with my AA Tsunami in a tank ring and a Rev on the centerfeed. It was small enough to shoot like a pistol, but could be shouldered too!
I'm currently building one to keep for myself.......for a while anyways....I keep selling them!
It was soooooo cool, I could snuggle right up against a bunker and was able to pop right out, no long barrel to worry about getting in the way. That's a good thing for me, at 6'1" and 245, getting compact is a challenge anyway!
With the barrel work, it's accuracy was on par with anything out there and I was able to pull off some pretty amazing long ball shots.
on top of that.....It's LOUD!!!!!!!
That's half the fun right there........
