For the most part, you can buy a 7.62x39 upper and just pin it onto a standard 5.56 AR-15 lower. You will need to use 7.62x39 magazines since the taper of the AK round is much more substantial than the 5.56 round. This is why 30 round AK mags have that very noticeable curve to them.

Hi Emmanuel, it will work, but you need to get the right mags that are compatible with the AR15 lower >>> https://dura-mag.com/duramag-ss-7-62-39-ar-15-stainless-steel/
Stay safe & have a great day!

Hi Emmanuel and welcome. It will not due to the difference in the 7.62x39 magazine design and the 5.62/.223 magazine well in this lower. Cheers and stay safe!
