That is why I specifically stated, “Anything but the 3 Gun” All the other Geissele triggers will be 4.5, single or two-stage.
I took the 3 Gun off my competition rifle and replaced it with a Hiperfire, it was just two easy to bump and run. Sounds like you would like the SD-C or the Tricon. I have the Tricon in a AR-308 SBR and it’s the only trigger that didn’t break.
I’ve had several Geissele since I bought the first one from Bill in 2000. They are solid and the company backs them.
