Penny,
Still stirring up controversy, huh. :nono:
Just kidding.
As you already know, I always install vent liners. I use white lightnin' and there is nothing faster.
There is absolutely NEVER any reason to remove, unless they are being replaced. and NO danger of them blowing out if installed properly.
Where most problems come from, are the screwdriver slotted ones that are easily removed, guys think they have to remove them every time they clean their guns. In and out, In and out, pretty soon it doesn't get tightened, or the threads get buggered up and out it comes.
A white lightnin when installed properly, is part of the barrel and must be removed with and ez-out.
Very fast, very reliable. Remember, and idiot can blow anything up. :blah:
