PErsonally I had trouble with the carlson wrench with the skeet and IC tube.

After I lubed and broke in the chokes, I went back to the supplied wrench with good success.

If I have a complaint it is that the second trigger may be a little light. Had it go off a little early when aggressively shooting Sporting clays. The fact is every time it did I hit the clays. That is something for me as I am a 60-70% guy.

It does oattern nice, but the best patterning gun I have is my arietta.
