Grendel dying cartridge..LOL

[King31]

The only negatives I can see going against it's popularity are the slightly increased cost of ammo (I reload so it doesn't affect me much) and the magazine situation. It would be nice if they were more widely available (none available locally to me) and if someone would come out with a reliable polymer mag for it. I look at the dozens of 5.56 mags I have and wish they would work with the Grendel. I wonder if Magpul has looked into it? Otherwise to me it is the most useful AR round made.

I've wondered this as well. My Magpul Gen2 mags hold 5 rounds with ease and function well.
