They have new erectors. I run several VX5HDs and VX6HDs. Fly all over the country with them, regularly dial them out to 1250 and back to my 100 yard zero - never had a problem with them. The glass on the HDs are phenomenal. Guys go buy a $400 VX2 or 3, put a CDS on them and get pissed because they don’t track like a $3000 nightforce...eye roll.
Also important to note - because leupold makes scopes at about every price point, they probably sell a 1000 times for scopes than nightforce or TT etc. its a numbers game, i bet the same percentage of nightforce scopes have problems as leupolds higher end stuff.
