"this mag does not work with all guns
i worked in my m16 but the m16 didnt function so i returned it and bought the a&k sr16
i kept this mag of course because i bought it as an extra for my m16 so now i use it in my sr16 it misfeeds unless you push it forward and even then it makes the gun dry fire
extremely annoying and bad for my gun, but it works (sort of)
if you are looking for a reliable mag, dont trust this one."
