My personal experience with it is - if you don't load it to capacity it works just fine. With 26-27 rounds loaded in the mag the gun barely ever jams. Fully loaded it does happen on occasion.
Also for sale is a ten round steel AR-15 5.56/223 magazine. It has also been barely used. We aren't in a 10 rounds mag state after all, so I prefer my Pmags.
Talking of which, I also have an extra 5 regular, non-window Magpul PMags brand new in the original packaging.
Those are $10 firm each.
Used Butler Creek Hot Lips magazine. 25 rounds 22LR.
