Is there any official data of the polymer used? How much heat can it take?
What is the official cold test? Any testing of having it down to minus 5 degrees F ( -15 degrees C) and dropped on the concrete?
I don't have problems with polymer mags, after all, HK, Steyr, SIG and Sako use them too. Some of these pictures are very nicely done for marketing and advertising - but if Magpul can publish some of the official testing data that will be great. Lots of nice pics of having the Pmags driven over by trucks-that is pretty cool, however, I am more interested in how the feedlips will survive on drops and heat. I would want o know how it will do if I smack the bottom of the pmag on some hard surface when it is attached to the rifle, or if the floorplate will separate from the body if the heel of the mag is dragged across some rough terrain.
