CorrectYeah see thats why i was wondering the length. I just bought a 12.5 Grizz and i put the 12.5 barrel on my norinco mag fed, and the 14.5 barrel (from the Norc) on the Grizz.
Now i wan't the tube on the Grizz to be flush with the end of the barrel. But i think the +1 will be short and a +2 too long.
