what failed? My sample size is pretty small but I have loved the optics I have from vortex.
with that said I haven’t really used them much as I have always chanced alpha glass but after being let down by a pair of Slc’s and an ats (no issues, just not any better then stuff for half the price to my eyes) I’m currently rethinking all my glass. I picked up a razor spotter that is amazing especially for the price I paid and I have a set of Japan 10x42 razors that I can’t tell a bit of difference from my 2020 model Slc’s.
I also am looking very hard at meopta products........
All scopes were mounted without loctite on the screws, torqued with a Wheeler Fat Wrench.
1. Crossfire ii: Mounted on 50 Caliber Muzzleloader, lasted 4 shots and the erector system broke and was rattling around inside. 4 shots, total.
2. Crossfire ii: Mounted on another Muzzleloader, fogged in the middle of a hunt. Had been shot 6 times total.
3. Diamondback (regular): Reticle rotated about 30 degrees while sighting in a Remington 700 270. Lasted less than one box of ammo. Re mounted 40 year old Leupold M8 6 Power with friction turrets and dialed it right back in.
4. Diamondback HP (discontinued since this happened): Lasted 3 shots on a 6.5 creedmoor, and the bdc reticle spun about 150 degrees inside and the parallax correction knob stripped and came loose.
5. Viper HST: Belongs to brother in law, there were 2 of them. One was killed first shot on a 300 win mag, one died after about 2 boxes on his 6.5 creedmoor.
6. Diamondback Binos: Focus knob stripped, but only from one barrel on my wife's first hunting trip (they're her binos)
7. Diamondback Spotter: Fogged on the first hunt I took it on, on opening morning, on a limited entry elk hunt in Utah.
Yup, I have been extremely disappointed. I won't spend a penny on their stuff anymore. Their warranty doesn't reimburse me if I miss an elk, and I don't care about a guarantee if their optics fail on a hunt and inhibit my ability to have success.
