No its okay, I included the stock choke tube and the tactical (Optional) to show the difference. If you look at the second post with the torn down pictures you see the tactical and right underneath it the standard one.
I believe the UTS-15 uses a Beretta style thread for the choke tubes, but one member on the bullpup forums said its a special Beretta thread, what ever that means.
But there is also an optional 7.5" barrel extension (I don't know if they released it yet...) that will be availible for those that wanna do trap shooting!
