Here are a few pictures of my custom CNC machined mag releases. All dimensions were taken off OEM release with a digital micrometer. These were made from billet aluminum and polished to a mirror finish. The mags have a nice "click" to them when inserted. My mag had a tendency to fall out on occasions but not any more. Also they match my polished barrel ;D. I made one for my GFs gun too. Next my Dad's but not sure what my future plans are for these but if things slow down a little who knows how many I can produce.
