Do the old stick mags work ?
I hope to upgrade when I leave
this stupid gulag.
If you have the new M1A1 semi-auto from Auto Ordnance (which is nearly exact to the military version except for semi, barrel length and magazine catch), to use a real mag from WWII or after, you need to oval-out the mag catch hole in the magazine in the military version. A file or Dremel works fine. This done, they work just fine.
