    Absolutely well made and exactly what I was expecting. I am guessing these are, all around, the best mags made. Love the 20 round capacity.

    Best commie compliant mags you're gonna find if you live behind the lines in a formally American State lol. Very durable & trustworthy. Will never have to worry about feed lips failing when stored loaded long term like most polymer mags can, even the top quality brand can have this issue which these mags won't.

    The best most reliable magazine I’ve found, better than Pmags by far in my opinion. I will buy again and recommend them to others as well.
