Carlson Long Beard TSS Mobil .650

[strum]

 I shot this choke a total of about 8 shots. Just didnt work with the Weatherby 18.5 barrel gun for me.
  Its has some gray anti seize on the threads. ( I use this on all my chokes) I'll be glad to clean it off it it bothers you .
How about $35 tyd in the US or maybe something equal value for trade ?
  Im shooting a 20 Remington now so some TSS ? or a tube for the Rem .
