Primary arm or Vortex Strikefire

Vortex comes with a lifetime, no questions asked, transferrable warranty. Primary Arms is a 1 year. However, the Primary Arms is good to go. I use one on a 12 gauge shot gun to shoot slugs and it handles the recoil fine and holds zero. Question is... how long will it continue to do so.

EDIT to the previous post... seems the Vortex Red dots come with a "limited lifetime warranty". Sorry about that. Not sure what it means but it might be something to look into.
