I have a 14.5" midlength gun that was doing something similar. I swapped the H2 buffer with a standard buffer and it works fine now. One more variable to eliminate.

I've had the same problem with both of my 20rnd PMags, typically when there are only 2 or 3 rounds remaining; which tells me weak magazine spring tension. No problems with the 30 rounders that I've been running for a couple years now.
At any point did you try your buddy's mags in your gun? You said that your mags ran alright in his gun, but you didn't mention whether you tried his mags in your gun.
My buddy has a problem with the CA modified 20 round PMAGS. Personally, I don't have a problem with them, but he says his LWRC A2 doesn't seem to like them.
I believe this has something to do with the spring in the CA compliant PMAGS being overly compressed with the 10 round block. The vendors of the CA compliant PMAGS have to make sure that LEO cannot fit 11 rounds into a 10 round magazine. This causes PMAG dust covers to not fit, making it very hard to insert a loaded mag into a rifle with the BCG foward, having to insert 9 rounds instead of 10, etc.
I believe these issues with 3rd party modified PMAGS are the reason that Magpul is looking into making official CA legal magazines.
We make A LOT of magazines (different colors, round capacity, and magazine types). While we test in as many different platforms, type of ammo, shooting schedule, etc. it is impossible to try everything. If anyone is having issues with our product please feel free to contact Tech Support and we will do everything possible to make it right.
Unfortunately it is not possible to verify a third party’s manufacturing process and therefore we cannot guarantee that our product will work after they (the third party) modify it.
On a personal note,
I take my job very seriously because I know what it is like to trust your life to your weapon. If anyone has any questions or concerns please feel free to contact me and I will do everything I can to help or run it up the chain to make sure it gets fixed.
* And before anyone asks, I cannot discuss the particulars of when any new products are coming out so please don't ask.
Thanks for the reply Jimmy. But its definitely a third party who adjusted the mag to meet the CA laws. With that said, any chance you will be making 10 round PMAG's in the future for sale to the public?
