Not sure on it - CompMag AR-15 5.56x45 10-Round Compliant Locked Magazine

I would add a separate mag lock for this thing as it pulls right off with some force. You think a LEO that wants to ruin your day out isn't gonna pull hard to remove one of these mags... hence eliminating the compliance with the NY SAFE act. I would buy this only for the neat loading design that could feasibly help clearing a jam....then again I got a weird bolt jam using some steel case and I don't know that the mag didn't contribute to that. Could have been a fluke. If it doesn't jam again I may come back and upgrade my rating. In terms of loading speed you're better off with an ejection port speed loader.
