Questions for Vulcan/Vulcan2/Vulcan Tactical owners

thats the only way to reduce the transferport size. by clipping it deliberately.

I would have bought the Vulcan 2 but for some stupid reason they did not put a power adjuster on it. Funny thing is their dart tranquilizer version had it included!

By power adjuster i dont mean the hammer spring adjuster of course. Thats something else unrelated.
 
In May 2018 I purchased a Vulcan tactical with the side lever cocking, and it shot so good In July 2018 i purchased my Vulcan 2 tactical from tony at talon tunes, and added a Donnie FL moderator, because it is a little loud without.. and this is what it can do at 46 yards .... enough said

Turning the barrel will change the alignment of the transfer ports restricting the air channel. I bought a used Vulcan from AOA and when trying to remove the shroud I saw the barrel turn. I called them and they were willing to work with me but I could tell they thought I had simply used excessive force and stripped the barrel indexing screw out of the barrel divot. After some difficulty getting the cap off of the index screw I saw I had no index screw. I was able to find a screw that would work and the barrel is now aligned and secure. Doing some research I was lead to believe some didn't have an index pin to center the barrel but can't state that as fact.

I'm new to the Vulcan and what I know about it is primarily based on the following link. Two videos show barrel removal/installation.
