OK, I ordered a couple of these… As usual desert fox shipped quick and product arrived promptly. These magazines are good. I would call them quarky… they seem to stick a little bit when the follower goes all the way up, you can fix this by taking a Dremel about a 16th of an inch off the end of the follower… And then noting the sides were the two stops are inside the feed lips of the mag. If those two things were done, I would say they were five star mags… They actually have a metal reinforcing on the rock in notch. I will definitely order some more
