I have a turkey barrel (the one with the fibre optic sights) for my Mossberg 500 12ga. My other barrels are threaded for the accu-choke screw-in chokes, but this one is not. I'm guessing that it has a fixed Full choke, but does anyone know for sure? There's nothing about it in my Owner's Manual. (I haven't fired anything through it yet). Thanks.
