The alum monocore is their signature design .The next most affordable disasembable product line seems to be Coastal Gun , using K baffles.
But alas '13 is the year to invest in handguns and evil rifles.
I bought a Zephyr when they changed the core design. I was a little pissed when my dealer got them in because he ordered a Zephyr XL for himself. They were not advertised yet but I would have bought one of those instead to help reduce first round pop which is my only gripe with the suppressor. However, it is my first and only one until my Octane 9 comes in.
