Does anbody make a .45ACP AR variant that uses Glock 21 mags? I can find .40S&W and 9mm ARs that usee Glock mags, but not .45. Thanks.

a bit pricey for me... I built a Greasegun lower, works just fine...

Thank you. I went to MGI's site, but that wasn't there when I clicked on products. Any idea what upper would work on that?

Oly or MGI blowback uppers would work.

I'd go with a Ronald Williams Gas Operated upper from here

ETA, worst case scenario, you'll have to tweak some feed ramps to work with the G21 mags, but shouldn't be a problem.

Someone in Maryland is making 45s but not sure about the mag, he may use Thompson mags.
I'll dig around and see if I can come up with more info.

I did a some asking, and it turns out that Kriss makes some 30 round Glock 21 mags. They are way pricey.

So why so set on G21 mags, interchangeability with a sidearm? There are a lot more, and a lot cheaper options with GreaseGun mags, and they are around $20 apiece. Also, there are half a dozen different greasegun lowers that will work.

Interchangeability, reliability, weight ,and nearly rust free are the big reasons.
