Only scope I ever had fail was actually a Leupold Vx-3. Still to this day don't know what happened. Never dropped or anything. But I called Leupold and they sent me a brand new one. I didn't lose any faith in Leupold. Sometimes things happen. Everything I have wears Leupold, Nikon, or Vortex.
I've dropped rifles, had them fall to the ground while leaning against a tree, bounced around in the truck, etc. Never has the scope lost zero from this.
Reminded me of something. My buddy and I were in the Guadalupes hunting. Actually we went up there a week before season and scouted every day, then hunted the two days of the season. We were on a rough, rough road in my Toyota 4x4 truck. We got down in this creek bed and drove up the other side over boulders that looked like bowling balls. As we were bouncing up the other side, I looked back in the bed of the truck and the gun cases were coming up near the level of the rails and coming back down to WHACK on the bed. When we got back to camp, both guns were way off. I zeroed 'em. Thankfully, we had lots of ammo with us, always take a lot of ammo.
I had the cheap Bushnell the Savage came with on mine and he had a Zeiss on his Browning BAR in .300 win mag. He swears by Zeiss, but he has a lot more money than me. In this case, neither scope held zero. I'm not sure there's a scope made that could go through that and hold zero, many would be beaten to pieces.
This is one reason I still regard Bushnell as a good affordable choice. I know it ain't the best, but I've owned quite a few of 'em and they've all impressed me mechanically, maybe not the best optically, but they held up.
I have this Bushnell Trophy on a .22 mag I traded a small motorcycle for. That scope, Japanese manufacture, is pretty impressive optically. It's really clear and sharp. The Trophies run around 150 bucks, like I said before, up there with VX1s and Nikons, but they're really good and under-rated on most threads like this.
I bought a new Banner the other day for my SKS to be used for night hunting pigs. I have this green laser with a really nifty scope clamp mount that adjusts to aim the beam exactly to the scope's field of view. The laser's beam is also adjustable to concentrate the beam for a more powerful spot and you can match the spot to the field of view. This allows me to see over 200 yards just fine and, supposedly, the green wave length doesn't bother the pig. We'll see about that. I've always used a red light and it was, well, it worked okay if you got your shot off quickly enough.
This laser is just awesome, though, and a whole lot cheaper than a FLIR.
I'd considered spending 50 bucks more for a Trophy. The Banner is Chinese and optics not as sharp as the Trophy, bu the Banner had a lighted reticle and I considered that important in a night scope. There are times when you can see on a bright full moon night, but can't quite make out the reticle. With the lighted reticle on those nights, I don't need the spotlight at all.
