Quoted: Maybe I have never experienced a strike because after I mount the silencer I take the time to inspect the alignment before I pull the trigger. |
I had two barrels threaded by the best in the business without relief cuts. They didn't fully seat the can and caused copper streaks on the endcap. I was very lucky.
You must sight down the bore from the breech to be completely safe when checking for alignment.
I had one bad A2 Flash hider that caused a misalignment. Only sighting down the bore would have found this. Again, very lucky.
It is worth the postage to send your barrel to the can manufacturer for their blessing. That still doesn't guarantee it will be right, but it puts the liability totally on them.
Your stomach will do flips when you trigger off a round and hear it zinging (tumbling) down range.
