This rifle doesnt get hot like my last one
While this might sound like a dumb question, I'll ask anyway.
Previous rifle: armalite m15 carbine midlegnth.
Current rifle: pws mk116 mod 1.
My armalite would just get smoking hot around the barrel. It had the standard hand guard. This pws doesn't seem to get hot at all compared to the other rifle.
Is it the vented hand guard? Isonite barrel? Profile? Gas system? Combination?
My guess is hand guard, but would like to know more. Does the type of barrel change how fast it can cool?
