It can, but when I see 15 guys in a group and there are 15 vortex scopes in the group and 12 of them have been sent back at least once that leads me to believe there may be an issue with that company.
Maybe they're just unlucky.
I've had a few Leupolds go back, two SWFA and I've seen a few Nikons fail. The leupolds had a lens coating issue and 2 that would hold zero. Both swfa's were bought used and abused and the parallex went belly up. The Nikons I guess an internal lens fell out.
So, out of the 20 or so leupolds I've owned for 30 yrs I've sent back 3. I have 4 swfa that have been beat on pretty hard and the 2 used ones went back. The Nikons weren't mine but they were new and just kinda fell apart inside, lol.
That's not hardly going 12/15 on returns on scopes less than 5 yrs old.
