Thompson Center Contender Super 14 223 Rem Blued Great Shape By Ingram. I have a used Thompson Center Contender 223 Remington rifle barrel for sale that was made by Ingram. This barrel is used, and it’s in good shape. It shows a few signs of use, but looks very good overall. It has a blued finish. See pictures for condition. This barrel measures about 14 inches long from end to end. Bore looks good, but it needs cleaned.
