I have a 2-stage CG on a Rem 700 and it is superb. I also have Jewell, the top 1-stage and an Anscuhtz on a PGWDTI and will switch all to CG, however I prefer 2-stage, as do snipers and many fullbore shooters. It is a drop-in with ADL trigger guards, but the lower part of the trigger housing "just fouls the standard BDL floorpalte assembly" according to Peter Jackson. Sam Adams, who just installed my CG R700-TSBR adjusted to 1.5kg second pull, said there was a "very small amount of machining" on the H-S floorplate.
We will advertise prices and details when triggers are landed. Pricing objective is to be similar to Jewell.

Peter
