I went shooting and this thing exploded on me. I will post pictures later. The lower broke into two pieces while I was shooting it. I thought the receiver exploded, but it was the lower. I had heard about this once before and I didn't believe it due to the amount of damage. I've probably shot _______ rounds over 35 years and never had anything close to this happening. The way they build their buffer tube, theres a thin sleeve inside and the buffer got caught on it and it ripped off the back of the gun, All I can say is this is a very unsafe product other than using it for a dedicated .22.
