Make a new barrel assembly for your Thompson Center Seneca or Cherokee rifle, or Patriot pistol. Our hook matches your tang, with very little file fitting required. The nipple seat is tapped for our short #PTC-S nipple for No. 11 caps, with 12-28 thread.

Thompson Center does not sell their plugs as a spare part, so we offer these nearly identical plugs for your use. Made in the U. S. A.

Use Birchwood Casey's anti-seize compound on nipple and clean-out screw threads, for easy removal after hard use.

Drilled for a powder chamber, you may enlarge this cavity, but it must remain smaller than the bore diameter, to prevent entry of a cleaning jag, which might become stuck.
