Just FYI.. Burris warranty works for 2nd owner too. I bought a FFIII from a friend.. and it quit working. Sent it to Burris and they sent me a brand new one with no questions asked.
If you are a veteran, I would look at Vortex. The guys at SportOptics.com can take care of you with a vortex red dot with military pricing, outstanding customer service with fast and free shipping. (Note: Not affiliated with SportOptics.com)
