I'm looking into martix milsim mags, I'm looking for reviews but sadly only found 1 and it is the evike one.
They are full metal and you can fit 200 bbs in each mag.

will this fit in the king arms m4 full metal? It looks amazing and the writing reviews look great so I just want to know if it does.
