    Kingslayer for budget USPSA Open build

    Posted by Rich Alloway on Dec 30th 2019

    Ever since I first heard of Swampfox Optics on the We Like Shooting podcast, I've been looking for an excuse to purchase a Kingslayer red dot optic, but didn't have a pistol to mount on one.

    Black Friday/Cyber Monday let me put my hands on a Springfield XDm OSP 9mm Tactical which as a threaded barrel and 3 red dot mounting plates for a great price. Swampfox's BF/CM sale locked in the deal!

    I used the RMR mounting plate that came with the XDm OSP to mount the Kingslayer and dry fired with it for several days before I had chance to head out to the range for some live fire. During indoor dry fire, I noticed that the dot would have a visible flicker while moving the gun on the 3rd setting down from the brightest.

    Using my 1000 fps highspeed camera, I found that the brightest setting did not show any flicker (100% duty cycle) and the other brightness settings had varying duty cycles; 7 frames on + 7 frames off for the 1st step down (50% duty cycle), 4 frames on, 4 frames on + 9 frames off for the 2nd step down (~30% duty cycle), etc.

    This is my first red dot, so I'm not sure if this is typical or not.

    In live fire, which I've been able to do 3 times since receiving the dot earlier this month, I've put about a thousand rounds through the pistol that this dot is mounted to and the flicker is noticeable on the 2nd and 3rd brightest setting as gaps in the dot cycle arc, if you're looking for it, but I don't think it's going to be a problem. The brightest setting does not flicker and isn't so bright that the dot blooms on an overcast day and also appears to be bright enough for even the sunniest days. I'm concerned about the battery life on the brightest setting, but will be carrying extra batteries with me when I practice or shoot a match.

    After zeroing the dot, I have not had to re-adjust it, even with 9mm major ammo which loosens the compensator! It seems to be holding the zero just fine.

    My father-in-law, whose eyesight has him thinking about putting red dots on his pistols and revolvers, has been putting off buying a red dot until he could shoot a handgun with one to see if it really would help. After putting several magazines of ammo through the XDm with the Kingslayer, he's now sold on getting one! After Christmas, I expect that he'll buy one or more Kingslayers for his own handguns.

    I'd have given this dot a 5-star review, except for the flicker. If all dots exhibit this, then I'd say the Kingslayer deserves the additional star. If others do not, then I think the Kingslayer designers should consider increasing the pulse frequency so the gaps in the recoil arc appear shorter (or may even disappear if the rate is high enough).

    Kingslayer on Glock

    Posted by James Dillard on Dec 18th 2019

    I purchased the Kingslayer to test as an alternative to the much higher priced Trijicon RMR. Upon arrival you can tell they take pride in their product, the packaging is well made and sturdy. Inside the optic and accessories are protected well by a foam insert. The Kingslayer mounted easily to my aftermarket Brownells Glock slide cut for the RMR, no wiggle room, no gap. Once mounted I test fired it to zero and the Kingslayer was already perfectly sighted in for 25 yds. The dot is bright and easy to see even in daylight. As a gunsmith who shoots a lot, I would highly recommend the Kingslayer as a red dot option for a CCW, and even competitive shooting. It’s one piece design with external battery compartment makes it a solid choice for use and a great alternative to the RMR.

    This little red Dot for the money is amazing. The glass is CRYSTAL clear and has held zero. I have astigmatism and the reticle is crisp! The only con is the battery life.
    Great job swampfox. Will definitely buy again

    Great Red Dot

    Posted by Colten on Dec 12th 2019

    The kingslayer should be called the RMR slayer. This red dot is sturdy, precise, insanely clear sight picture, and looks badass on any firearm you choose to attach it to! I highly recommend this for anyone looking to upgrade their weapon, you won’t be disappointed.

    Kingslayer for Ruger MK III

    Posted by Chris F. on Dec 6th 2019

    I bought my Kingslayer for a Ruger MK III, and so far I am very happy. It was easy to mount and zero, the glass is wide and clear. I would definitely buy again.

    Absolutely love this optic. Great lenses, and dot brightness. Amazing that it fits and RMR footprint at a fraction of the price and in my opinion might even be a better optic. Super military friendly company which is also a plus.

    Good Value

    Posted by Brian McKinley on Oct 19th 2019

    Purchased this optic for a rmr cut 19LS build. Fit was perfect and I was pleased to find that the dot was easy to pick up even in bright light.
    At the range the optic was easy to zero and performed great.
    First experience with Swampfox and I will be back next time I need an optic.

    Great RMR-compatible optic!

    Posted by Nathan S on Oct 19th 2019

    This is a great optic! I selected the green dot option, and very impressed with it. It took minimal adjustments to get on paper, and just a little longer to get it set for 25 yards zero for my G19 build. It came with a lot of extras in the box: tools, mount for picatinny rail, cover, microfiber cloth. The packaging was great, solid foam to keep everything safe even through the worst conditions that any carrier could render to the box. I do notice that my reticle is canted ever so slightly, maybe 3 or 5 degrees. Not a big deal to me. I will definitely get more of these in the future to pop on my carbines and pistols!

    Coming towards 1500rds and its simply amazing. An other video will post soon. Glass is like everyone is saying, CLEAR. One of the clearest and cleanest glass and dot ive used within double the price range.
    Original battery died in 20min but once replaced it has not had an issue. Cr2032 energizer for the win. Bring a spare

    This thing has been awesome. Very robust red dot. Highly durable. It’s definitely waterproof. I threw it into the bottom of a 20 degree creek for an hour. Took it like a champ. The Dot is very clear and precise. The mount it comes with is very nice. Did I mention how awesome it looks. This thing is definitely hanging with the more expensive priced optics. Keep it up Swampfox

    Great product

    Posted by Colt kessler on Nov 2nd 2018

    This is a great little optic, it functions and preforms well and mounts very easily. Looks and feels great. Only used it just a few times now but from how it’s been working for me so far, I am very satisfied. If I’m being picky about it, the only thing that I would say is that they could have a better guide on what kind of adaptor plate you would need for mounting it to a pistol. Swampfox sent it out next day and the costumer service was very good. On a side note, after my product was shipped it took quite a while to get to me but that was USPS’ fault. Only thing I would recommend to Swampfox is to use fedex or ups instead of to postal service. Otherwise I am very happy with this little optic and I give it a 10 out of 10!

    Super Kingslayer

    Posted by Wayne on Oct 24th 2018

    Just installed a Kingslayer on a new 9mm carbine. Extremely clear glass with a nice Round dot that the intensity is easily adjusted. I can very easily co-witness through the optic with my BUIS due to the extremely clear, distortion free glass.

    This is an amazing product with all the right features and quality that will provide many years of service. I can't recommend this enough!!

    Quality, super easy to zero

    Posted by Daniel on Oct 23rd 2018

    I recently purchased the Kingslayer from y'all, I put it on my 300 blackout 10.5" barrel pistol build, it zeroed super easy, I love the quality of the materials, the lens is super extraordinary, the clarity is off the charts, it held a zero like other red dot I've seen in its price range! I will definitely be buying more in the future different kind of optics also from you all.

    Shotgun Beating

    Posted by Ed P. on Oct 22nd 2018

    I had the opportunity to use the king slayer this weekend in Nevada for a two day shot gun course and I was really impressed. It took a beating and the red dot stood on target every time. I can't wait to use some of your other optics. I referred a couple buddies to your site.

    Posted by Clynn Korney on Oct 21st 2018

    Bought this for my first AR build. Found it on Expertvoice at a reduced price. Read the specs and saw it was a US company. Looked like a good deal. Just mounted it on my rifle but haven't had a chance to use it. Seems to be built well. Controls are easy to use and red dot is bright and clear. Mount is sturdy and secure. I like that it came with its own tools. Gave it 4 stars because I haven't shot it yet.

    Posted by Jon C on Sep 7th 2018

    Great little item, sturdy build, seems on par in terms of quality with more expensive big brands. was accurate out of the box at 100yds. dialed it to 50yds and it is dead on. excellent value if it holds up which seems likely at this point
