Videos tagged with BCM KeyMod Rail Covers

This video demonstrates a practical heat test for Bravo Company USA (BCM) KeyMod rail covers on an AR-15 platform. Conducted by Mrgunsngear, the test involves firing 100 rounds through the rifle with covers installed over the gas block. Temperature readings before and after firing are compared to evaluate the effectiveness of the covers in mitigating heat transfer to the shooter's hand. The test highlights that while the covers significantly reduce handguard temperature, the barrel itself still reaches high temperatures.
