||I have an Ares G36CV. I love the gun. I bought some Kingarms mags which have their ups and downs. Mostly they stick.
I picked one of these up because everyone raves about the PMAG.
First of note. I have had no issue dropping this out of the magwell. Push the release with my forefinger/middle and out it drops into the dirt.
Second this is a very solid mag. I'm pretty sure it's made out of the same nylon reinforced plastic my gun is mad out of. At least the outershell.
I can't comment on the feeding as it seems the same coming from my kingarms mags. As in no feeding issues at all.
I noticed that the curviture of the mag is less than that of a normal G36 mag. Which leads me to belive that it will fit into a M4 pouch nicely. I can't confirm this because I don't have one but I'm pretty sure it will.
Now my reason for 4 stars.
This is an excellent product.
It functions well. It can use the ranger plates. It's thinner (which is a drawback in a way). It doesn't have the nubs.
But, when inserted into my magwell it wobbles. Where as the Kingarms mags don't. And in the end I can't see a reason to pay 3x the price for virtually no performace gain. With the King Arms I just shaved off about 1mm of plastic around each mag at the top and they drop out just the same as the GMAG. Since I don't shoot anything besides semi and almost always have 2 mags out of 5 left at the end of a game I can't see a need for 30 more rounds.
So while it is a well built product and it does look nice in the end it has left me wanting for the price.
