Most Helpful Positive Review Kinglsayer
I had an issue with my original Kingslayer in that it would drain the battery and Swampfox customer service went above and beyond in my opinion. They got me a replacement ASAP. The new Kingslayer is in my hand and has functioned very well. I only have roughly 300 rounds with it on top of my gun s...

Most Helpful Negative Review Buyer's beware, mount failed after 400 rounds and the company won't cover the replacement.
The mount this thing comes with is cheap. The screws stripped out the mount after about 400 rounds through my ar9. I reached out to the company to have them send me another mount and they told me i would have to pay for shipping because I didn't buy it directly from their website. The only reason I ...

Not impressed

by Phil, Verified Owner from WA, United States Written on April 1, 2026
I got this for a dry fire trainer to mimic my EDC setup. Some things I should have noticed before purchasing: the reticle is huge. The circle around the dot is more distracting than it is helpful. Also, the battery tray is so bulky that it interferes with the sweat guard on my typical holster setup. It’s fine for dry fire or probably AirSoft, but I would not mount it to a real firearm because it doesn’t seem very impact resistant and the windage/elevation screws have no “click” when you adjust them. Mine doesn’t “shake awake”, I have to hit a button to get it to come on, which is a PROBLEM for an EDC optic. I have experience with Trijicon, Aimpoint, Bushnell, Holosun, and Primary Arms optics and I would take any of them over this. That being said, I managed to figure out a holster solution so I can train at home without doing a bunch of administrative handling of a real firearm, so it does the job.
Pros:
  • Price and install ease
  • battery tray on side
Cons:
  • Durability
  • reticle
  • Battery tray size
Best Used for:
  • Dry Fire

Pretty great sight for not a lot of money.

by Jim, Verified Owner from IA, United States Written on March 22, 2026
This sight is built pretty well and has a nice reticle. The cost/quality ratio is pretty good. Are there better sights? Of course, but they cost quite a bit more.

Thoroughly impressed

by Carl, Verified Owner from SD, United States Written on February 4, 2026
I wasn't initially sure what to expect of this optic but after one friend had recommended it to me to try I can safely say this thing is well worth the money, it feels high quality and has nice glass to it, just make sure you get a mounting plate that works for your cut as this one has a kingslayer cut but does come with a picatinny mount

Swampfox Kingslayer on an ultralight !

by Dmitch Man, Verified Owner from CA, United States Written on April 29, 2024
I added the Kingslayer to an ultralight build. Mounted it at a 45 for up close & personal. It does the job just perfect ! With its mounting options ya can’t beat it for the price ! I’m planning to get another one. The only thing Swampfox could do better is have the nice protective cover fit a lot tighter. A Heck of a nice product and an awesome addition to the build.
Pros:
  • Awesome project at a great price!
Cons:
  • None
Would recommend: Yes

great red dot

by Deputy Marshall, Verified Owner from NY, United States Written on March 17, 2024
Used the swampfox king slayer on a modded G22 gen3 .40. Holds zero after many rounds. A little wider than your average Red dot so I wouldn’t put it on a slimmer sized slide. But on the G22 frame it fits and looks great. Very easy to install. I like the side battery insert as well.
Pros:
  • Easy to mount
  • Wide lense
Cons:
  • None
Would recommend: Yes
