Won't release after first usage
The pin at the top right shifted after the first sixty rounds. The drum could not be released without removing a takedown pin to gain access to the top of the drum. I feel like a beta tester after spending so much for a pair of these to have a failure on the first run!
A fail
Was feeding flawlessly but jammed while simply loading. After carefully following the repair instructions, drum broke beyond repair and is being returned. Great customer service but this device cannot be relied on.
Failure
Retaining pin on right side of the feed tower partially backed out during use. The magazine would not drop out of the magazine well and could not be pulled out. I had to remove my upper, use a pin punch and reinstall the pin to remove the magazine from my rifle. I know longer trust this product.
Stay away from this product!
Just like everyone else I had a grin from ear to ear when I received this in the mail. That grin faded real fast when I loaded 10 rounds and then followed the instructions to unload the 10 rounds. I could not get the loading lever to release and discovered that the follower did not return to the loading port. After attempting to release the wound up follower with a few shakes, the follower slammed back into the original position and the internal mechanism broke into multiple pieces. Magpul does warn not to do this, but there was no other way. No quality here and I would not trust this mag. First Magpul product to disappoint.
It Seemed Like a Good Idea at the Time
...so I bought one. I should have thought it through. First, for the cost of this, you can easily buy six 30-round magazines and have three times the capacity. Second, at this price, you're not going to want to just let it drop out of the mag well and hit the ground, much less leave it behind. For LEO or military units, those two might not be issues, but what will be is, third, this takes up more space than two 30-round mags, and is heavier, actually decreasing the amount of ammo you can carry and get to quickly. The headshot for me, however, is the fact that this is extremely difficult to load--mind you, not "load quickly," just "load." Magpul says that the last four rounds may require some extra effort to get in (my paraphrasing); well, the first 56 aren't much fun, either. It took me about 30 minutes to fully load it, and most of the time was NOT taken up with the last four rounds. Three hands would have been helpful, along with massive thumb strength to operate the loading lever. Loading two 30-round mags takes me about five minutes, tops. Then, there's the disassembly required to clean and lube it. There may be those for whom none of this matters; if so, this product is up to the high quality standards that Magpul is known for. I have a lot of Magpul products and think that they are well made, better than the competition, and worth the money, but, sorry, Magpul: I think that this product is a bad idea executed extremely well.
