tbird430,
Welcome to the carbine forum.
The detachable tube was partly because of the hole being drilled off a bit, causing the area to crack. This was one of the causes of rejected receivers. Other makers also had detachable, mostly early on. The spring is the same.
The only part Quality made was the receiver. All other parts were contracted out.
