KAC M4 RAS Heat Dissipation

I’ve updated my earlier heat dissipation graphs with the KAC M4 RAS. This is the railed handguard used by the US military on Colt M4 carbines and similar weapons. I did not have rail covers on the handguard during this test, because I was also comparing it to some other railed handguards.

Here are the handguard temps:

And the barrel/gas block temps:

Not only did the M4 RAS transmit less heat to the shooter’s non-firing hand, it also allowed the barrel to cool faster than the plastic handguards. This is in addition to its other benefits, such as mounting various accessories.
