I’m putting together an upper with a WOA 20” Predator bbl and trying to decide on what handguard to get.
Several of the handguards I’m considering install with shims behind the barrel nut that are used to time the handguard. Will the use of shims between the barrel extension and the barrel nut have any detrimental effect on accuracy? I’m inclined to think that it might.
