I have 3 of the complete .22lr CMMGs. Twist rate is 1 in 14 or so.
Accuracy is, typically, about 12" at 50 yards. Failure rate is about 1 in 20. Magazines are difficult to load past 15 rounds, even with the loading tool.
Yikes, that was harsh. Was the first one bad, the second worse and the third trash?
