I sold mine about 10 years ago for about $3000 with a nice Burris 3-12x scope.
This was a G2A that had the "bridge" for the scope and for tensioning the barrel. It had a SS Krieger 1" barrel. It looked nicer (IMO) than the OP rifle. This is the actual photo of the rifle before I sold it to Security Arms in AZ:

It is always interesting when someone grabs a pic you post to forum and then puts their name on it as if they had taken it.

$16K - no. Maybe $4K, at most $5K.
Originally the stock was about $1200 IIRC, and they would mod your rifle (operating rod, barrel, etc) and return it to you for about $2300 including the stock - more if you wanted additional work on it (heavy barrel, barrel tension, etc.)
I liked mine, I maybe should have kept it - it was very precise; I got under 0.5 MOA groups with the right ammo. But I am 60 years old and I am not going to be lugging around a 12 pound sniper rifle in the field very often, especially one that only has a scope.
