I just dropped a Geissele SSA trigger into my Sig516G2. All I can say is "WOW!" It feels like a new weapon! The two stage trigger along with the reduction in weight to 4.5 lbs makes a world of difference.

For those of you considering this modification, you won't be sorry!

You are correct. The I put an SSA trigger in my 516 a couple of years ago with the exact same results. My go to rifle.

Yes, the aftermarket AR triggers tend to make a major improvement.

I've always been a big fan of the Wilson Combat TTUs.

Aside from one AR that has a Geissele in it, ( only option I could use for this large FCG pin Colt, ) all the others get TTUs, including my 516.

I put the SAA trigger in my Colt 6920 a year or two ago. Don’t know why I waited so long, but I do wish I’d gone for the SAA-E.
