You might be the only person in WA buying a 10 rd AK mag... Probably everyone else stocked up prior, just plan to go to ID or OR, or are waiting on the injunction decision. We should win that legal battle, it violates federal case law and the WA state constitution...not that the dems care.
Anyhow- There are still plenty of steel 5 and 10 rd mags out there that came with MAK90 rifles. On the 5 rd versions, if you swap out the follower with a tapco polymer one, or just trim down the sides of the steel follower, they will hold 9 or 10 usually.
Don’t think I have enough of the small steel mags to sell them off (might though), but I probably do have extra tapco followers for making the 5 rounders into 10’s. Saw several of the mags at a gun show this last weekend, so I know they are around.
