Last month I picked up a new M&P 15 Sport. I've only had the opportunity to run through a couple of 30 round mags but noticed that the barrel heats up rather quickly.
Since prices have come way down lately, I was able to pick up a lefty SlideFire for $135 that showed up at my door yesterday.
For obvious reasons, one of my first objectives will be to burn through a 30 round mag all at once - just for the hell of it.
However, I don't want burn up the barrel on my brand new rifle.
I've read the barrel heat thread downpage which has me a little concerned.
I'm thinking that after burning up a mag I should practice with my other guns and let the barrel cool down to "hand touchable" before using the SlideFire again.
Just curious what others with a SlideFire (or not) would recommend so that I don't kill the barrel.
