[Zack The Ripper]

I had a ten pack of these and for the first couple months they fed very well, but after some vigorous use they fed terribly.

I tried removing the top of the follower on a couple to see if maybe that extension on the follower was catching; no joy. I tried lubing; no joy. I tried cleaning the mags AND my hop up; no joy.

Mind you, I was using these with a G&G SCAR only, so who knows what the real problem was. I can tell you though that after buying four true PTS mags, the feel between the two is like night and day. Much denser polymer on the PTS mags than the BP versions. The color matching is also better on the PTS (kinda a given), and I have NEVER had a single feed issue with them on full auto or semi.

Its really chapped that the real PTS mags don't come as package deals or for less expensive individual prices, but after using multiple brand mags, the PTS PMAGs are bar none my favorite. Having a car drive over them and being filled with mud and still performing after a quick clean speaks for itself.

I will say that I have a bunch of random "Chinglish" brand STANAG mags bought for $8 each that perform almost as well, but not on full auto, they are my "semi auto only" mags.

My only conclusion is that the spring in the BP versions simply were not made with enough tension and after being loaded and depleted multiple times that they simply didn't have enough tension to force the rounds into the hop up. I say this as I would only fire one round on full auto and maybe 5/10 on semi. I ended up selling them all for dirt cheap as they were too much of a pain to deal with.
