Working great! - Mean Arms 9mm Ejectored EndoMag - 3 Pack

I got the three pack. Have worked flawlessly in my build. For reference I’m using a generic milspec upper. A ballistic advantage 11” EPC barrel and a faxon 9mm gen 2 Bolt. Put them in some old gen2 pmags I’ve had laying around for a decade.

Did a total of 300 rounds out of these mags. About 100 each. All three ran smooth without issue and ejection is really strong. I did had to shave a little material off the back of some old gen2 pmags. You’ll see if you use the faxon bolt or a similar one. It’s not much of a problem and the bolt itself will wear the feed lips on the mah down. The bolt slightly rubs on the back of one of the feed lips. You can sand paper or easier, just use a knife to just remove a very tiny amount of material for clearance and it works fine. Otherwise it gives the bolt a little resistance going into battery until it wears in or you remove a small amount of material.
