I spent an awful lot of my young adult years watching guys with loads of money show up at gun clubs and firing ranges with their fancy guns and bash anyone that had an AK, SKS or a Mini 14. I was often ridiculed for owning a Mini 14 because according to most AR15 owners, it couldn’t hit the broad side of a barn at 100yds, but I was hitting 2 inch groups all the time. These guys would always rave about how accurate the AR15 was and that they never had reliability issues, but I was always watching these guys clear malfunctions or blame magazines or ammo for all of their jams. I will tell you that I got tired of the mentality and avoided AR15s for a very long time just because I could get the job done with a Sturm Ruger Mini 14 for just about every job I ever need it for.
I did notice that shortly after Pmags started showing up on firing ranges the amount of jamming I saw dropped by 99%. I don’t know when the last time it was that I watched an M4 or AR15 jam that was using Magpul Pmags. These magazines are virtually indestructable. I’ve seen youtube videos of guys driving trucks over them and they still worked. I have heard of a few problems with them not dropping free from magwells of some manufacturers, but that’s a minor production issue and not really the magazines fault. Even if you live in a un gun friendly State, you can still get 10rd magazines.
