Got a Carlson's .683 extended turkey choke that I shot just a couple of times in a Beretta Xtrema II (Optima Plus threads). Shoots a good, even pattern with TSS but a tad too open for my tastes. Like new. Also have a set of like new Tru-Glo Pro Series Magnum Gobble Dots off of the same gun. TG944C. Think they also fit Browning Gold, Franchi, Benelli Montefeltro, and Winchester SX3. $50 for both shipped TYD.
Will split as well. $22 for the choke tube TYD. $32 for the sights TYD.
