The case hardened frame lightweight AYA ten is a double trigger gun, should give you no trouble with doubling. Yes, Utah makes a good suggestion to open the chokes slightly to relieve a bit of friction at the muzzles. However, don't spend much money on that project. I would save my money for the eventual installation of the Brileys. I don't think my gun will ever show any damage even though I have not opened the chokes. I have a "Baggo" tens and the AYA is my favorite for waterfowl. The only modification I am contemplating is the installation of sling swivels, a useful accessory for a serious waterfowl gun. Yup, $600 is a great price for a high condition AYA lighty.
