I have had it driven in my head that heat is the enemy of barrels, along with rust and politicians.
That being said, while at the range last weekend I found out that an AR gets hot after a mag being fired at a reasonable pace. Not dumping the mag, but not waiting 30-60 seconds between shots either. It was my first time shooting an AR. I am used to shooting levers and bolt guns, as that is what I always had and grew up with.
I would like to assume these are designed to take some heat? Or am I wrong? I have a Ruger MPR with a free float barrel. I fired one mag and the barrel was hot enough I could only touch it for 2-3 seconds. After about 2 minutes it was luke warm. I take the mag out, leave the action open, and had the wind blowing through the barrel.
The guy in the stall next to me shot 3-4 mags in about 10 minutes and then cases his rifle and left.
Maybe I'm overthinking it, but I like to take care of my stuff. Is it best practice to let the barrel cool down between mags? Or are these things made to shoot a few mags at a reasonable pace before needing to cool?
