This video popped up on youtube today. I had never seen it before. C Products Defense announcing their 20 round 6.5 Grendel Duramag. I didn’t notice anything about functioning in 6 MM ARC.

Isn’t there some kind of rfq for a 20 round mag... for the 6arc? Guess they want to sell it commercial too...
I've been using the DURAMAG SS 10 round magazines without any issues. They have worked great. I went ahead and ordered two of the 20 round Mags.
I used one of the 10 round mags yesterday with out issue, they look identical to my E Lander side by side.
The spring in the CPD seems a little weak compared to the E Lander though.
