DPMS M4 .22 upper - good magazines that work?

[Morris]

About to pull the pin on that upper but any ideas on magazines that work well with the upper?

[kabob983]

Is it a standard STANAG size magazine? If so S&W, CMMG, and Black Dog Machinery all make mags, I've used the CMMG and they work reasonably well.

Looks so and DPMS said they were so the upper would fit on a standard lower.
