How do those "integrally suppressed barrels" work?
How do you clean em? Do they last only so many rds. or what?
Some are ported early in the barrel to keep rounds subsonic, then they open up to baffles, and the tube is a sleeve that fits over the whole barrel.
The Liberty pinnacle is a 4.5" barrel inside a 16.5" tube full of baffles, so the barrel opens up into a 12" suppressor, so it is stupid quiet.
Many companies integrals take down from the end cap, then the tube slides off exposing the barrel and baffles for cleaning.
