That's an interesting flash eliminator design. Was this a working prototype or a concept idea. The trouble with a No8 replacement is that it's primary role is to be a training aid for the real McCoy. And now, there's the SAT/laser range trainer. Not as reliable as a VW I have to say. Now that I think about it, not as reliable as anything else I can think of! Oh, yes...., where were we...... Ah, yes....defective SAT range rifles!
