S&B's are not what they were with regards to durability and reliability, and are not the "best". There are a whole bunch of military shooters not using their 4k issued S&B's. Despite what some think- zero retention and reliability matter.
I sat in a room years ago and observed an exchange between a USMC Scout Sniper (who's had a History Channel program done about him) and the former NCOIC of 5th SFG's Sniper School discuss S&B scopes. "Schidt and Bend-Overs" as the marine referred to them. The SF guy laughed.
Every one of the initial buy scopes had to be returned because they wouldn't track and hold a zero.
