12 Gauge. Any length.

Looking to convert my old classic to add a Turkey Choke.

i have an 870 express turkey gun which ive been trying to use for waterfowl. its a turkey barrel with sights so it doesnt ork well for wingshooting for me so im looking to sell or trade my barrel and get a longer barrel for waterfowl. its a 23 inch barrel, mossy oak camo with tru glo turkey sights front and rear with a never used super full turkey choke. 12 ga. if youre interested
