Go to www.vortexoptics.com and look at all of their optics and the description of each. Down at the bottom of the description... it tells what is included with each product... it appears that high end and low end of the optics are covered by the VIP warranty.
Just had to add a note. I got my diamondbacks and nomad back after 7 business days. They were not only repaired, but cleaned and the nomad was nitrogen purged and sealed again. They look great! Best of all it was all free and required no proof of purchase. Awesome service!
