Thanks for the input
I'm not digging into anecdotes though I'm sharing personal and first hand experience with leupold and vortex issues.
I had two AMGs that had parallax failures, unfortunately I'm seeing G3s go down at a rate that ain't acceptable either.
Recently I was shooting with a buddy and his Mk5 was tracking way off at 1100-1300 yards, mirrors my tracking problems with a vx6 and vx5.
I like good glass but if the optic has tracking or zero retention issues then it's useless.
Don't try to tell me all scopes fail at the same rate cuz that's 100% untrue.
I hear WHAT you are saying, but I don't think that is the right premise.
The MK5 is the winningest optic in the PRS the last couple years. Does that mean its the best scope out there? NO. It means Leopold sponsors a large number of the best shooters. If it wasnt a solid scope that tracked, no one would run it. Most competitors would not run a piece of gear they don't trust, even if its free. Hard to win with a scope that doesn't track. It was also selected for the MK22 and is on virtually all non SOCOM sniper rifles.
The G3 is also very popular and is proven. There are a large number of them out there, like the MK5, so you will hear of more issues with them due to the numbers out there.
My buddies NF 735 parallax was fucked up at the Texas 2 day last month. It was stuck and would not move. He shot the match with a fixed parralax. Shit happens.
If you shoot enough you will see everything break or fail. Some things more than others but its actually pretty random. You will also see alot of people who THINK they have a bad scope, but its due to their incompetence. Things like not torquing action or screws, loose rails/lugs, poor reloading, poor shooting skills, bad ballistic data/input, ect.... I have seen where the scope is blamed and then a competent shooter looks at it and realizes its something else. I would bet about half or more of the scopes sent back for issues are actually not defective, and its user ignorance/error.
What you or I or most people see are like .001% of the optics in the wild. Our little sliver is not representative of overall durability and tracking of the optics market.
Your or me or anyone on this site does not know what rate scopes fail. We may think we have an idea, but the only ones who know are the manufactures and none of them are sharing that information. And even if they did, it would be bullshit.
So where does that leave us?
Pick an optic with the features you like AND one with a great warranty department/CS so WHEN something breaks or fails, it minimizes your down time. Anyone serious about competing or doing this for a living is going to have a backup gun/ backup scopes anyway, which is why they exist. There are companies out there that will take Months if not half a year to fix a broken scope. Then there are ones that will have a new scope at your door in less than a week.
