I bought a Jard 1 pound trigger for a 10/22 years back and have kept it as 10/22s come and go in my safe. It is way ahead of any parts replacement tune-up I've seen, better than the Ruger BX by a lot. Not sure it is quite as good as Kidd or Volquartsen .. lighter pull weight but a touch more creep, so a tradeoff.
Whether someone else would appreciate it, don't know. I'm used to Jewell triggers set 4-6 ounces on my centerfire varmint rifles. If you like that, then I'd say the Jard is worth a try. If you don't appreciate it, or don't think you need it, then probably don't bother with the Jard.
... and, finally ... this is a sample of 1. Maybe every other trigger Jard ever made sucks, I don't know, all I know about is **my** particular example and it is pretty damned good.
