I honestly kindof doubt it. Also, the Steiner employee I spoke with truly seemed passionate about the product. Not like he was trying to be a good CS rep, but like he geeked out on this stuff and legit loved the technical aspects.
-Schott glass
-Tested on scar H, full auto, 25 guns, run hard for a day
-Design tested to 50bmg barret recoil emulating machine, unknown Gs
-Each scope. Individual test 350 rounds 762x51 recoil simulating accelerometer then tracking and all functions of illumination and zero retention verified.
-All parts US sourced material and machine work, except "maybe a screw or O ring or something like that from China".
-Internal mechanisms similar to t5, but with design flaws corrected.
-Side impact testing similar to 556 recoil performed.
-This Steiner employee felt the scope is the durability equivalent of Nightforce NXS line, in their opinion.
This is just the opinions and datapoints provided me by one Steiner employee during a phone call to their 1800#.
