About a month ago I posted an install how-to and review of the Strike Industries Drop-In Free Float Mega Fins handguard. Some of the readers were curious about how well the Mega Fins dissipated heat, so while at the range I did an impromptu test. Admittedly it wasn’t as controlled of a test as I would have liked, but it did achieve the desired result.
After dumping a couple of magazines the handguard remained comfortably warm to the touch. I am sure with sustained fire it would get pretty hot, but it does seem that the heat sink principal of the Mega Fins rail is a solid concept.
The MSRP of the handguard tested is $149.00 and can be found on Strike’s website here.
