I have also had discussions with Corrie about this "new" 2 stage trigger CA is offering in lieu of the Geissele option they used to offer. The "new" trigger is made by Schmid and the one CA is offering was vetted by Monty from a bunch of various offering available from Schmid. As I told Corrie, if Monty says it is good to go, then I have no doubt it is in fact a very good trigger. Centurion Arms in part was forced to make this change in triggers due to the fact that, like everyone else after Geissele's BF sale, they could not get any product from Geissele. They ran out of triggers that they had in stock, and thus had to make the change. I'm not sure if the Geissele option will return or not. On their website Centurion is offering a new AMTAC line of rifles that do feature the Geissele SSA, so they are getting some from Geissele now, it appears. I personally think having a $100 2 stage upgrade available is a nice option.
