It’s not a 5.56.
It’s 5.45. Look at the Tapco 5.45 mag here:

Tapco doesn’t even make 5.56 mags.
“Tapco doesnt even make 5.56 mags.”
That rifle is probably a 5.45 but I’m 100% sure so I say either for now. We also don’t know if it was the weapon yet.
But Tapco does make 223 and Galil AK magazines. They make everything.
