Question on RRA handguard
I have an RRA Operator Entry Elite. It has the half smooth half quad rail hand guard . I notice the smooth section of the grip gets noticeably hotter than the Quad Rail portion. My question is: would a full quad rail would be cooler to the touch? It isn't unbearable, but it gets pretty darned hot. I'm not sure if the smooth section is a heat sink, or if it gets hotter just because it is closest to the chamber.
Thanks,
Jeff
More surface area (as in found in the railed section) dissipates heat more efficiently.
