The thermal elongation of aluminum is astronomical when compared to steel. Not to mention the fact that most free float tubes that I've seen are not thick enough at the base.


The front sight base/gas block of my 10NMFA is not aluminum. If I mount a sight on it I expect it to stay put. I might mount a light or bipod on the floating handguard, but I will not expect it to hold zero, nor will I expect the handguard to touch the barrel.

That covers everything that I want the equipment to do. Am I missing something?
