I have been thinking recently that I should own a .410. Being a bird hunter that already has too many SxS's I'm not sure what I would do with a .410. But, I think I need a .410 so I've been looking. I found an AyA with 30" barrels. Very nice condition and at a fair price. The only thing that stopped an immediate purchase were choke tubes. This gun was originally fixed chokes of IC/Mod. but has had Briley tubes installed. My first thought was that this gun had a barrel regulation issue and this was an attempt at correcting that issue. Other than observing if the tubes are centered at the muzzles any hints on determining why these tubes may have been installed?
