DONT fall for it-korean glock mags

[chucklenut]

I was evil,I switched the springs and followers out with Glock mags. Then took the Glock mags to Glock and had them switch out the springs back to OEM. So I had less then $10 each for an extended Glock mag. No issues out of a Keltec.

Then I sold the Keltec

nice

If you can find the KCI AR mags, try some. They are steel HK knock offs and I've had no issues with them, even kept one loaded for a year with 28 rnds and it ran fine.
They're not easy to find now, but when I do, I get a load of them.
