picked up a polish tantal couple weeks ago at my local shop. yes, its a century. and no, it does not keyhole. so far im loving it. just need to get some more mags for it. ive got a case of 7n6 coming in tomorrow. i think the only thing im going to do is switch out the stock with a bulgarian ak74 wood stock and throw a US palm pistol grip on there and call it a day.
