Works like it should.
                            
                        
                            Bought 2 for the Beowulf and they work as good as the ones from A.A.  None of my polymer mags would feed reliably but no issues with these.

                fantastic mil-spec
                            
                        
                            These are great for the range, and they fit in all standard mag pouches. I got 4 of these to add to my kit, and haven't had a feeding issue with any of them, even in my worst quality AR. They're great, and they work just like the ones I was using in the military. They're easy to disassemble and maintain, and they can store rounds for several months without an issue.   I haven't tested these with something like a Mossberg MVP though, but would be interested in giving their 10/15 round mags a shot from that platform.

                            I have got many of them, and they work very well. I will buy more for my needs. They fit my Bushmaster and never had a feed problem. These  magazines are well made, and just work.

                            I have a Smith M&P-15 and the mags work fine, if you load them in the gun with the bolt closed I just have to slam them in a little harder than say my other mags. For the price they ran bullets thru the gun just fine great use and lose mag.

                            Bought five of these. They worked OK. No problem with fit, loading, or inserting.  Cycled ammo well. I'll buy some more.

                            Bought 2 of these. One inserted and dropped out correctly, the other one did neither. Have not run ammo through them yet. Will have to sand and repaint the bad one to get it to fit. Poor quality control.

                I bought a bunch of these
                            
                        
                            I bought a bunch of these mags just to have a few to keep in the closet for hard times. When I was function testing them, the only problem I had was that a couple of them (three of the ten) wouldn't engage the bolt stop, so after the last round was fired, the bolt would still close. Not a bad bunch of mags though. They function fine other than that, and I'm not displeased with them. They are just about what you would expect from a mag on the bottom end of the cost spectrum.
