Burris, I'm on the fence with them lately.  I bought three brand new  Fullfield II on Amazon last month and had to send all three back because the eye pieces were so loose, I could hold the scope and move them about 1/16" in each direction.  Refunded from the seller (Burris Store?).  Disappointing.  Then less than two weeks later, I had two older Euro Diamond 3-10 scopes that I bought used that both ended up getting sent in within a week of each other, and both were replaced due to no parts available.  Initially they were getting replaced with Veracity 2-10, but I called them and they were going to let me pick whatever I wanted, and if the cost was higher than the $804 Veracity MSRP, I'd have to pay the difference.  Of course, if the cost was lower, then that was on me, they wouldn't allow multiple items for one item, which I get.  So I have two Signature HD 5-25x50 Plex on the way, which are going to end up sold since I already replaced the Euro Diamonds.  So not disappointing on that part.    I've been buying and trying lots of different stuff in the last year and a half (kids grown and no debt except house) and it's been a shit show, to be honest.  These were all new in box scopes I've sent back to either the retailer or to the manufacturer: 6 out of 8 different Bushnell scopes,  4 of 8 Burris, a Trijicon,  2 Leupold (no surprise, my track record with them is the worst out of any company), 1 of 3 Hawke.  There's been 5 used scopes (Bushnell, Leupold, Burris, Simmons)  that I bought on ebay or gunbroker that all had issues and were sent in for warranty.  Funny, or oddly, enough, I've had more issues with the stuff that $400-$1100 than the lower priced stuff that ran $150-$200.  It's par for the course for life this year though.
