Heck, I own a sear and I might pick one up, just to have another option for my hosts.
Though, I don't know that I want to be a first adopter. I was one of the first batch of buyers for the Franklin BFS for the AR platform (before they required the guns to sent in and installed by them), when they were touting it as "drop in". After a ton of trouble getting it running in my Spikes Tactical lower, involvement of my local 07/02, and worthless calls to Franklin for Support, they finally told me that I needed to pay for installation and have them do it.
I promptly sold my BFS to someone else (who, ironically, put it into his Anderson lower and got it running with no difficulty on the first try).
