If you are unsure if the standard ZEROED 22 or the shorter 22 K is the right choice for you, then have both with the 22 Plus. The ZEROED 22 Plus comes with a standard size ZEROED 22 suppressor AND an additional 22 K outer tube. Whenever you’re ready to have a shorter suppressor, simply swap the standard-length tube for the K tube, remove two baffles, then re-asssemble. Boom, now you have a ZEROED 22K.
