I had not bought a new suppressor in many years, and when I went in to pick up my new cans, the dealer told me to bring in my rifle, and they would rod them to ensure the alignment was correct. This led to the first stupid conversation of the day; I said the cans are not dedicated to any one firearm and will be moved around, so that's not an option. I was advised that the manufacturers might not warranty a can if the alignment was not checked before shooting them. After a second idiotic conversation, I left the dealer without checking their alignment. I figured I might buy some suppressor rods ($60.00 ea) to confirm alignment, but I have owned suppressors for many years and have never heard of needing to do this. Is this seriously something that needs to be done now?
