and the difference may be,,, the Traditions Vortek may have been designed to handle the larger flash hole,
the question to CVA should be, Are their weapons designed to handle the larger flash hole and are they prepared to Guarantee that by drilling out a larger flash hole, the weapon is still "SAFE" for the shooter.... BUT that's for CVA to decide not for you or anyone else including Don Luhr to decide..
Democracy is two wolves and a lamb voting on what to have for lunch.
Liberty is a well-armed lamb contesting the outcome of the vote.
