Both Crosman and Umarex have done a great job doing this and the Umarex Legends CO2 Blowback Full Auto M3 Grease Gun is another example of a well thought out and what I expect to be very popular Full Auto BB Rifle. Their Legends series encompasses guns of the later era which I personally really like since they are harder to come by in their real steel versions, so having them available in an easier to acquire version that you can even shoot in your back yard is a win win for everyone. I am also happy to confirm the high capacity double stack 60 round magazine seemed to feed pretty good for me only miss-feeding once during my testing while doing the Chronograph portion but it got back on track right away.
