Swampfox Kingslayer Problems With Practical Solutions

1. Battery Draining Issue:

As a seasoned user of the Swampfox Kingslayer, I’ve encountered a recurring concern with its battery life. This sight is designed to be always on for quick readiness, but unfortunately, this leads to the battery draining much faster than hoped.

The Kingslayer uses a CR1632 battery, which is smaller than the typical CR2032, and I’ve found it running low sooner than expected, especially during extended use sessions.

The stated battery life is around 200 hours on the highest setting and up to 3000 hours on the lowest, but in practical use, particularly at higher brightness levels, the drain is quite noticeable.

This is not just a minor inconvenience but a significant issue for reliability in scenarios where you rely on your red dot for important tasks.


Addressing the battery draining issue in the Swampfox Kingslayer requires a few simple measures:

  • A simple step I’ve found crucial is always keeping a spare CR1632 battery.This practice can save you from a lot of trouble, especially during extended outdoor trips.
  • Additionally, turning off the sight when not in use significantly conserves the battery for extended periods. It’s an essential habit that has greatly enhanced my experience with the Kingslayer.
  • Another aspect I’ve learned is the importance of using high-quality batteries. They significantly affect how long the battery lasts, particularly under demanding conditions. This might seem like a small detail, but it’s an effective strategy for maximizing battery life.

Moreover, adjusting the brightness settings to match the environmental conditions also plays a significant role. Using lower settings whenever feasible has helped me extend the battery life substantially. These strategies have turned what initially seemed like a drawback into a manageable aspect of using the Kingslayer.

2. Durability Concerns:

One of the primary concerns with the Swampfox Kingslayer is its durability. Despite being marketed as rugged equipment for field use, it can be more fragile than expected.

The main issue is the housing’s susceptibility to crack under stress, especially in demanding range environments. This vulnerability to cracking was surprising and disappointing, considering the rugged use cases for which such a device is intended.

It’s not just an inconvenience to have a damaged sight; it’s a matter of reliability and trust in your equipment.

In my experience, while the Kingslayer is a robust piece of gear, it only sometimes withstands the rigors of intensive use with some care. The performance and accuracy of the sight are paramount, particularly at a crucial moment.

To ensure the Kingslayer remains dependable, it’s essential to handle it with an understanding of its limitations. Recognizing and respecting these boundaries can significantly improve the lifespan and effectiveness of the sight in various field conditions.


Tackling the Swampfox Kingslayer’s durability concerns involves adopting specific strategies. One critical aspect is handling the Kingslayer with extra care, which I have found essential.

Being mindful of the impacts and stresses during use and transport can significantly reduce the risk of damage. It’s about understanding the limits of your equipment and respecting those boundaries to ensure longevity and reliability.

In instances where damage does occur, contacting Swampfox for a replacement is straightforward. Their team has consistently responded and understood the issue, greatly easing the situation.

From my personal experience, Swampfox’s handling of these concerns demonstrates its commitment to customer satisfaction and the reliability of its products. Proper care and utilizing its responsive customer service can significantly mitigate the Kingslayer’s durability issues.

3. Hard Button Controls:

The Swampfox Kingslayer is a remarkable red dot sight, but it still needs quirks. One particular aspect that can be a bit of a niggle is the stiffness of its button controls. These buttons, used to adjust brightness and power on/off, are hard to press.

This becomes noticeable in situations where quick adjustments are necessary. The resistance can make it challenging to operate the sight efficiently, which can be frustrating during high-pressure moments or when wearing gloves.

This issue is more than just a matter of comfort; it impacts the usability of the red dot sight, particularly in the field or at the range. Quick and precise adjustments are crucial, and hard-to-press buttons can slow down your response, affecting the overall performance of the equipment.

Regular use tends to ease the stiffness somewhat over time, but it remains an area where the Kingslayer could improve to enhance user experience and efficiency.


The good news is that the problem of complex button controls on the Swampfox Kingslayer has improved over time and with usage.

Initially, the buttons might feel stiff and rigid when pressed, but they become more accessible when they break in. Consistent use is critical to making these buttons more responsive.

Personally, I have found that using the sight regularly and practicing quick adjustment drills help me become accustomed to the buttons’ initial stiffness.

This practice gradually alters the feel of the buttons, making the sight more efficient to use. It’s a matter of adapting to the Kingslayer’s unique characteristics.

Through regular engagement and familiarization, what once felt like a hindrance becomes a manageable aspect of the site’s operation, ensuring smoother and quicker adjustments during usage.

4. Tiny Screws for Windage and Elevation:

A notable challenge with the Swampfox Kingslayer is the tiny screws used for windage and elevation adjustments. These screws are indeed small and can be challenging to handle, especially in field conditions or when wearing gloves.

Their size makes the adjustment process cumbersome and raises concerns about potentially losing them during maintenance. The precision required for zeroing the sight demands an ease of adjustment that these tiny screws can sometimes hinder.

In various scenarios, especially those requiring quick, on-the-fly adjustments, the size of these screws can evolve from a minor inconvenience to a significant impediment, affecting both the efficiency and accuracy of the sight.

Over time, I’ve developed a certain finesse in handling these screws, but it’s an aspect that could be refined by Swampfox to enhance the overall user experience.

The Kingslayer’s precision and reliability are exceptional, yet the adjustment mechanism could benefit from a design that facilitates use in diverse shooting conditions.


To overcome the issue of managing the tiny screws for windage and elevation adjustments on the Swampfox Kingslayer, I’ve discovered some practical solutions.

A specialized small screwdriver or adjustment tool has been the most effective one. This makes the handling of the screws much more accessible. Finding the right tool for the job is crucial and has significantly improved the precise adjustment process.

Additionally, practicing with these tools in a controlled environment before heading into the field has made me more familiar with the feel and operation of these screws in a low-pressure setting.

This preparation has proven beneficial, particularly in demanding conditions, where quick and efficient adjustments are essential.

Thus, with the right tools and some practice, the challenge posed by the tiny screws can be effectively managed, ensuring seamless operation of the Kingslayer in various scenarios.
