Will the 9'' rail cover the gas block on a standard 16'' barrel?

Featured Answer
A
Answered by John, member, from TX, United States, on February 26, 2019

Not sure if you’ve already purchased the handguard but it all depends on your gas tube length. Best way to find out is to measure from the end of the top rail on your upper receiver to the end of your gas block.
