I bought a Norinco .22 ATD from Sports Authority back in 1994 for $99. I still have it and still shoot it quite a bit. The only problem I ever had with it was when the part that prevent the feeding of a second cartridge from the magazine fell out and got lost. Numrich had the same part but for a Browning. After some fitting the rifle was as good as new.
BTW has anyone else ever noticed that the design of the bolt, recoil spring and striker and trigger group on the Browning .22 auto hears a striking resemblance to its much larger machine gun cousin also designed by John Browning.
