To zero: Yes you should put on some aftermarket parts. but hey, we're not talking about dremeling any part of the weapon , just some 10 to 15 dollar mags, even if you don't use them right away, get a couple to practice with .
Allways start slowly, and test acouple of times as you go along. remember , you cant' put back on metal. once you get em figured out, it takes about 5 minutes to do one. i do think the E. german ones with the big rib down the back, and the little hole in the front top of the mag catch, is the easiest to do . just screw down a little metal screw in the top of that front catch, and waa, laa,! there is your bullet guide/jump.
