Look them over closely Norm, the AMP's aren't for everyone.
They are big and noisy and not a gun to shoot indoors if that is what you are limited to. They have been a handloading project for most of their life but the new owners have SBR out of Georgia selling new ammo for $50 a box and it has been getting good reviews.
I have read reviews from two owners so far and they have been impressed with the quality and the functioning. I was told by Patrick that mine would ship last week but I have not heard anything. Getting ready for SHOT could have slowed things up.
