Barrel Nut install on M4E1 upper/handguard Combo Review by David
Barrel nut must be placed on barrel before gas block. Not sure what review above refers to.
Teeth on wrench that came with assembly would not clear the base of barrel to engage the slots in the nut. It may have been capable of being forced down the barrel base, but I was not going to gouge a beautiful new SS barrel. After a slight amount of custom filing on the wrench teeth, it slipped over the barrel fine and presented no problem.
This is a unique and clean design that I am looking forward to working with. (Posted on 12/26/2016)
