Two Triggers, the gun might be fitted with Teague chokes with flush tubes. They are quite thin, similar to Briley thinwalls. Teague uses a "taper key" to tighten and loosen the choke tubes, they don't have knotches for a conventional choke tube wrench. Teague choking is relatively popular in the U.K. and I see them from time to time on U.S. sporting courses. Check them out on Teague's site. I hope this helps. Silvers
