They always break. 3 for me. They are made out of very CHEAP plastic, and If you acidently let the slider "snap" to the top of the mag, it will break every time!! Do like I did...take a small chunk of alunimum & a file and make one. It will take a couple hours but its easier than it looks.......and..you wont have this problem .
