Hi everyone,

I’m considering the Kahles K540i. From what I’ve read, it has top-tier optical performance and a massive field of view, but I’ve also heard multiple reports about it failing.

For those of you who have purchased and used this scope, could you share:
  • What caliber you are running it on
  • How long you’ve had it
  • Whether it’s still holding up well, or if you’ve experienced any issues
I’d really appreciate hearing your real-world feedback before I make a decision.

Thanks in advance!

You'll find reports of every scope brand failing. I wouldn't let that in itself deter you from buying a K540, I don't think failure rates are high or anything to be concerned about.

However, when a Khales does fail it will likely have to go to Austria through Swarovski USA, which is a process that will leave you without a scope for a few months. I had to send a Khales back recently (older model), and I was without it for approximately 3 months.

In the unlikely event your scope fails, Khales will take care of it. But you will be out of a scope for a few months. That's definitely a point worth considering.

I know of 3 people who have bought these and all of then had to send them back for elevation turret issues.

One was broken before even got mounted on a rifle, the other was on a 22lr, so it's not a recoil thing.

I'm hoping they get it sorted out and the design modified as I really want to buy one of these.
