Honestly, the SSA is just a fantastic two-stage. The take-up is super smooth, then you hit that crisp wall, and the break is like glass. I put this in a 5.56 build with a mid-length gas system, and it really complements the rifle's precision. No adjustability needed, it's perfect right out of the box.
