I have an upper that I am wanting to attach a LaRue FF and then have the flash suppressor permantly attached. The bbl is 14.5"
I know that the LaRue has to be installed first because you have to remove the FS to do so.
What problem may this cause in the future, say if you gas tube goes t/u or what not. I'm tempted to just throw a KMC RAS on and be done with it. But, I have been told that the LaRue is a better system.
