      1. Take the old mag bottom off.
      2. Take the Arredondo extension, note that it slides onto the narrow portion of the mag first.
      Put it on and remove it several times, it makes life easier
      3. Remove the spring and follower from the old bottom plate
      4. Take the mag spring and follower and re-insert them into the mag
      5.Take the Arredondo base and using it as a piston push the mag spring into the mag
      6. Using your thumb (which one depends on RH or LH) hold it in the mag
      7. Take the extension and slide it onto the lips of the mag starting from the narrow side
      Voila, +4

      Thanks. I will get started on that.

      Buy a S&W M&P 15 round mag - $39 - you can find them on GB or elsewhere. Order an Arredondo S&W M&P mag extension from Dillon Precision or elsewhere for $17 + shipping.

      You'll need to hack the mag release opening - the Steyr opening is above the M&P. Take care measuring.

      When you start dremeling or filing, start low, and then work up toward the top of the mag. That way you won't have the mag too low to feed.
