One of the many Airsoft “myths” you’ll read on the internet are that Real Sword AK’s are picky about magazines. Rather the contrary, these can be adapted to function off of virtually any Airsoft 47/AKM pattern magazine in production. 9 times out of 10, this is simply a case of having to file on the back of the magazine catch until the magazine locks in place. In this customers example, I have adapted some G&P 150 round Midcaps to fit by doing some light filing on the back of the magazine catch. Testing shows that they feed perfectly.
