My opinion. It’s a pipe turned down to a certain diameter. All marketing. I can put, Midas, Carlson, Xtreme, or Briley in my Browning and my scores won't change. If I miss a target it’s not the choke. Although Extreme puts out a pretty choke tube, the extra money can be spent on time with a coach or ammo. Just my 2 cents.
I took some on trade last year. The longer parallel section surely doesn’t hurt anything performance-wise. They are very light. I was impressed and ended up buying a new coated set. Good people to deal with. Quick service and delivery. Way back when, they manufactured and supplied Krieghoff with their titanium choke tubes.
The only reason I used extended chokes was to protect the end of the barrel. Easier to replace the choke than the barrel. Of course, you need special chokes for 7.5s or 8s or cold days or bad hair days etc. LOL
