The pictures Ed so graciously added to the beginning of the thread, (because I can't figure out how to do it!..

) shows the Nylon reinforced MEC-GAR mag bottoms with my effort to dish the knobs for better purchase when shooting?... Where as Rich used a 5/8" end mill, I used a 3/4" and took it to the max, both have there appeal but, I would say it is most likely what we had on hand was what got used!

I am probably going to stay with the 3/4" because it is out to the max and feels very positive for the shooter in me.. but, aesthetically, the 5/8" is by far more preferable...

... Either way, it is an improvement to the MEC-GAR concentric ring offering... The last picture is a normal day at GT's work space! (next qty. 5 Numrich drums going out!) It can change to messy and stormy in a heartbeat!...

... Best to all, til...lat'r....GT...
