I have one 17(15 is all I try), it was the worst. If you shoot the whole mag you won't notice this. I also had to polish the ejector just a tad, that helped as well. Mine had that stovepipe problem, and the brass would get hung up by scraping the lower part of the chamber. I only loaded a little for this round, I do plan on going to a bushing die. That will prolong brass life as well.
I have looked at my 5.56 brass, and in general, ARs' don't pamper brass.
SF:
On the last forum there were pages written about how poorly C-Products magazines were made or worked. In this case, it was true. CP Grendel magazines are pretty poor and no one else seems interested in making them. This has gone on since the Grendel came out.
Of all the magazines CP produces (or produced) for the Grendel, according to the guys on the Grendel forum, the 17 round magazine was by far the worse. Very few guys had any that worked at all. I believe it was their design so I wouldn't bother with them. Chalk them up as a loss and buy the ten and 28 round magazines. Between these two magazines, the 28 round magazine is more dependable. Not saying you won't get one of five that still won't work but the 28 round ones are more dependable.
