I bought the .22 jet barrel. Now I own a topper jr 490 with serial # starting AC. Have a .410 26" barrel mod. choke and the .22 jet barrel they are all in very good condition. I attached the barrels and they fit tight and fired safely. Did not have enough jet ammo to sight just enough to confirm it is safe to shoot and firing pin hits dead center. Am now considering selling. Can anyone tell me what a fair asking price . Have ammo coming from reeds ammo supply. Has anybody dealt with them and what was the outcome?
