so this won't take AK mags, like a sporter should?
I don't think just any sporter will take AK mags. You need a "D" or "M" model. Or there are some that have been kit converted. I could be totally wrong about that (not all Sporters taking AK mags). But unless shown otherwise I don't think this rifle takes AK mags. At $285 it's a good price for a Chinese SKS. I don't know how the detachable mag affects 922r since it is an American made magazine. If I were to buy it I would disassemble it until I found out the answer to that question. I think you can still find the original Chinese SKS mags. I believe they have a five pointed star on them.
