The WASR's are known to have problems. Yours is probably the exception to the rule. They originally came into the country as single stack guns which were converted to accept regular AK mags. Some people like their WASR's but most people have serious problems with them. On the other hand, I have heard nothing but good things about the MAK90 and have handled over ten of them and have never had a problem with any of them. The Navy Seals chose the Chinese AK out of all the AK's in the world. The Mak90 is the same gun except for the the stock and bayo lug. If you put the right number of US made parts into it you can convert it back to it's rightful AK form. I would bet my life on mine. I highly recommend them to everyone, hands down.
