I have come to the conclusion that I have not been super happy with AR rails that are really thin and light weight. This isn't because they are bad quality or easily damaged, its because they become almost too hot to handle in hot weather or simply in a magazine or two without a glove. Before someone says I need to "man up", I carried an M4 in the summer in Afghanistan and got into gun fights with it. I usually wore gloves but the times I didn't, I could still handle my rifle. My BCM rail became so hot last summer in OKC (102 degree day) in half a mag that I couldn't even grip the rail and it was still not comfortable with a glove on. I am starting to really consider going back to a thicker rail to mitigate this issue as I like to shoot without gloves. Also the most likely situation for a shooting with my AR-15 is home defense, probably in my underwear or running shorts (sans gloves).
Anyone else come to the same conclusion? I know the geiselle do it better and my centurion is a little better, but I am almost tempted to go back to a simple a2 heat-shield with an impact weapon components light mount and save the $ for ammo.
