Close but no cigar - Amend2 AR-15 6.5 Grendel 10 Round Magazine

I'll start by saying, this is a better option than a standard ar mag if you're using 6.5 Grendel. I really wanted to like this product because there are so few mags made for this caliber, and for the most part I didn't have any issues with the feeding. I bought 2 mags and one worked ok, the second one only took 7 rounds and nothing I did was able to get more than that in the mag. The only other thing I didn't like was these are very strange and difficult to load. You have to push the round down at least 1/4" and then slide it back under a strange ledge. They did this to make it more like a single stack mag at the top and double stack at the bottom to improve feeding, but it made it very hard to load and I'm not sure if it helped at all. This also makes it impossible to use any kind of speed loading device if you have limited capabilities and need that assistance. The fact of the matter is, these mags are expensive, relative to other options, and I don't think they are worth the added cost. I purchased 2 steel, traditional, double feed, 6.8 Grendel mags at the same time and they were cheaper, far easier to load, smaller profile, and I didn't have any issues with them. To be clear, if these fit all 10 rounds and functioned perfectly, I'd give it 5 stars, even if it was harder to load but that wasn't the case in my sample size of 2.
