A friend of my father-in-law had one, which I had a chance to shoot briefly.
I wasn't trying to shoot groups, just plinkly at a few cans. So I don't have a real opinion on accuracy, but even the owner said it was only average. If I remember correctly, he said something about 1 1/2 - 2 groups.

I do know that the thing is god awful ugly. The recoil was more than I expected, based on other 308's that I shot, but not terrible. The worst part was probably the muzzle blast from the short barrel.

Overall I wouldn't buy one, but they do seem to have a following.
