Great trigger, good price.
You can also buy the SSA & put a lighter trigger spring in & have an SSA-E.
MM
IAW Geissele, they're not the same trigger, the SSA and SSA-E have different breaks by design and weight. Watch the 18 minute mark:
"Carrot" SSA VS SSA-E which is lighter and crisper (19.2 minute mark in the video)
