yeah, the theory is that the endcap won't loosen when screwing on muzzle attachments. I learned that when I bought the muzzle attachment for a bar 10 gspec, and the threads were not biting at all, the nov. barrel also has a slightly larger ID than the gspec stock outer , but it was minimal enough that it would bite a little if they were the same direction threads.Wait the main threads that connect to the outer barrel are negative on his?
