Hello, Bolson. I also am a single-shot rifle fan. You might want to check with Sinclair International or Brownells..they are affliated now. I know they have a nylon one for the TC Contender. What I do..and here a lathe come in mighty handy..I drill or ream out primer pocket for slip-fit on cleaning rod. Depending on caliber..I also bush case neck..brass stock works well & I used to soft-solder these in but, now I use Locktite bearing retainer. While it may not have the length of guidence of a longer bolt-action guide, it does help keep the rod/jag from wearing throat.
