I bought a NORINCO JW25A from CANADA AMMO last fall. I asked them if they sell spare magazines, was told no, but CZ magazines would work. I bought a CZ 10 rd polymer magazine, which fit the rifle. I went to the range, loaded up the magazine, inserted it in the rifle, and discovered the rounds tilted upwards and would not feed into the chamber. After a few attempts, I gave up. Do not buy CZ magazines for this rifle.
