my phone auto-corrected AK, to "so", lol. the mag release just looks like an extended release that you can buy anywhere...you have to pull it to release the mag...so somehow you need to rock the mag out, while pulling on the release...if you can do that with one hand, then bravo, but the way is, I could not. So for me at least, there's no point in having any kind of detachable magazine, if you have to use two hands to remove it.
More importantly though, can the magazine be inserted on a closed bolt?
