I've had a few triggers over the years and I've never been a "trigger snob". Usually I rocked the stock trigger....till i got into precision rigs, then all that went out the window.
Imo, the LaRue MBT is the "new" RRA 2 stage. The RRA was THE go-to trigger for a quality 2 stage for decades. I have 3 MBT's and like them. Usually they are a place holder for something else (usually a Geissele HSNM). I do have a permanent 1 in my 22lr AR and my 10.5" AR and really like them. I also have HSNM in 3 precision rigs (223, 224V, and 308). I did have an SSA-E for a short time, but someone wanted to trade straight up for their HSNM.
If you just want an upgrade over the stock trigger but not go to the extreme as a HSNM, then I'd say MBT based on price alone. Dont get me wrong, any of the Geissele's are great but since the MBTs are $50 less, they are a great value.
