Today, we dive into the review of the Killer Instinct Fatal X. Killer crossbows have often been hit or miss for us, though their recent models tend to land more on the “hit” side. Naturally, I was eager to get my hands on the Fatal X and had the privilege of writing this review. Previously, I also reviewed the Killer Instinct Ripper 425.
The Pro package arrived well-equipped, featuring a LUMIX 4×32 IR-E Scope, a Sled Rope Cocker, a quiver, three 20-inch HYPR bolts (390 grains) with field tips, and a stick of rail lube. Additionally, the crossbow comes with a lifetime limited warranty, covering standard non-wearable parts for the original registered owner.

Size and Weight
The Killer Instinct Fatal X features an adjustable AR-style stock, which measures 29.75 inches when collapsed and extends to 31.50 inches for a customizable fit. This adjustability accommodates various shooting preferences and arm lengths, enhancing comfort and stability for shooters in different positions.
One of the standout features of the Fatal X is its compact design. With an axle-to-axle width of just 9.75 inches when uncocked and a mere 6.25 inches when fully cocked, this crossbow is highly maneuverable, making it ideal for use in tight hunting blinds or dense wooded areas where space is limited.
Despite its durable construction, the Fatal X maintains a relatively lightweight build, tipping the scales at just 7.2 lbs. This balanced weight distribution ensures a comfortable carry during long hunts without sacrificing the crossbow’s rugged durability or performance. The combination of portability and compact dimensions makes it a strong contender for both seasoned hunters and newcomers looking for a versatile and reliable hunting tool.
The Killer Instinct Fatal X impresses with its well-thought-out design that emphasizes both functionality and aesthetics. Its AR-style adjustable stock offers a modern, tactical appearance while allowing users to customize the fit for maximum comfort and shooting stability. The skeletonized frame not only enhances its visual appeal but also helps to reduce overall weight, making it easier to carry during long hunts.
The crossbow’s slim profile, measuring just 9.75 inches axle-to-axle when uncocked and an ultra-narrow 6.25 inches cocked, is a game-changer in terms of maneuverability. This compact design is perfect for hunting in confined spaces, such as ground blinds or tree stands, without compromising on power or accuracy.
Durability is a cornerstone of the Fatal X’s construction. The robust materials used in its frame and limbs are designed to withstand the rigors of outdoor use, from harsh weather conditions to rough handling in rugged terrain. The high-quality camo finish not only enhances the crossbow’s tactical look but also provides additional protection against scratches and wear.
Optics
The Fatal X is equipped with a high-quality LUMIX 4×32 IR-E scope, specifically designed for modern crossbows capable of shooting at speeds exceeding 300 FPS. Its compact, slimline design seamlessly integrates with the crossbow, ensuring a sleek, low-profile appearance without compromising performance.
The scope features multi-reticle aim points, allowing for precise targeting across various distances. Rheostat brightness illumination in red or blue enhances visibility in low-light conditions, providing a tactical advantage during dawn or dusk hunts.
Exceptional clarity is achieved through multicoated optics, ensuring sharp and bright visuals even in challenging environments. The 1-inch monotube construction, combined with a fast-focus eyepiece, allows for quick adjustments and target acquisition.
Engineered for rugged conditions, the scope is nitrogen purged to deliver water, shock, and fog-proof performance, making it a reliable companion in unpredictable weather and demanding terrain. This thoughtful design ensures that the LUMIX 4×32 IR-E scope complements the Fatal X’s precision and versatility.
Cocking
Cocking the killer instinct fatal X with its integrated Rapid Draw Cran (RDC) system is very nice. It’s a great cocking crank. A downer is that the crossbow does not contain a decocking feature. The integrated RDC system makes it easy to cock this powerful crossbow at any moment quickly and quietly
Cocking the Killer Instinct Fatal X is a straightforward and efficient process, thanks to its user-friendly design and included accessories. The Pro package comes with a sled rope cocker, which greatly reduces the physical effort required by distributing tension evenly across the bowstring.
Benefits of the Sled Rope Cocker:
- Effort Reduction: Reduces the draw weight by up to 50%, making the process manageable for shooters of various strength levels.
- Even String Alignment: Ensures consistent and accurate shots by keeping the string evenly tensioned.
- Compact and Portable: Easy to carry and use in the field.
For those seeking an even simpler cocking experience, the Fatal X is compatible with crank cocking devices (sold separately), which further reduce the physical effort and are ideal for extended hunting sessions.
By combining ergonomic design and practical accessories, the Fatal X ensures a smooth, safe, and efficient cocking process every time.
Trigger
The Killer Instinct Fatal X is equipped with a precision-engineered trigger system designed to deliver a smooth, predictable shooting experience. Its crisp trigger pull minimizes any unwanted movement during release, helping shooters maintain accuracy at various distances. The system has minimal trigger creep, ensuring a clean break that enhances consistency with every shot.
Safety and reliability are built into the design. The trigger mechanism automatically engages the safety whenever the crossbow is cocked, reducing the risk of accidental discharge. Additionally, the Fatal X features an anti-dry fire system, preventing the bow from firing without a properly loaded bolt. This not only protects the crossbow’s components but also ensures user safety during operation.
Overall, the combination of a responsive trigger, built-in safety mechanisms, and reliable anti-dry fire technology contributes to the Fatal X’s reputation as a high-performance hunting crossbow. It delivers both precision and peace of mind for hunters seeking dependable performance in the field.
Performance
The Killer Instinct Fatal X proves itself to be a highly accurate and dependable crossbow during range testing. Straight out of the box, it offers tight shot groupings and impressive consistency at various distances, living up to its reputation as a high-performance hunting tool.
At 20 yards, the Fatal X delivers pinpoint accuracy, with bolts grouping tightly on target with minimal deviation. Moving back to 40 and 50 yards, the crossbow continues to perform exceptionally well, maintaining precision with only minor adjustments required for distance and windage. The multi-reticle LUMIX 4×32 IR-E scope assists greatly in maintaining accuracy, allowing for quick and efficient target acquisition.
The crossbow’s 405 FPS velocity ensures fast bolt delivery, minimizing flight time and helping to maintain trajectory accuracy even in less-than-ideal conditions. The smooth trigger pull and stable design contribute significantly to maintaining accuracy over extended distances. Even when tested in low-light settings, the illuminated reticles enhance visibility and help maintain performance.
The compact size and narrow axle-to-axle width make the Fatal X easy to maneuver, whether shooting from a standing position, a blind, or a tree stand. Its lightweight build also helps reduce fatigue during longer range sessions.
Overall, the Fatal X excels in both precision and performance, demonstrating consistent results across varying distances. It is a reliable option for both target practice and real-world hunting scenarios where accuracy and speed are critical.
Recommended Accessories
To enhance the performance, convenience, and versatility of the Killer Instinct Fatal X, consider adding the following accessories:
Arrows
Though the Fatal X comes with three 20-inch HYPR bolts, investing in additional premium bolts can improve both accuracy and penetration. Look for bolts with consistent weight and straightness for optimal performance.
We recommend using the Killer Instinct HYPR 20-inch Carbon Crossbow Bolts for the Fatal X. These bolts are crafted from lightweight yet durable carbon, featuring a dense grain structure that enhances penetration, stopping power, and knockdown strength, making them ideal for taking down large game.
Each bolt is fletched with 3-inch vanes, which provide excellent stability during flight, ensuring consistent accuracy. The moon nocks fit securely onto the bowstring, offering a snug, reliable fit and ensuring compatibility with all Killer Instinct crossbows. These high-performance bolts are a perfect match for the Fatal X, delivering optimal performance in both accuracy and power.

Broadheads
For hunting, it’s essential to swap out the field tips with high-quality broadheads to achieve better lethality and penetration. Both fixed-blade and mechanical broadheads are effective, depending on your hunting preferences and the size of the game you’re targeting.
If you’re looking to pair your bolts with top-tier hunting broadheads, we highly recommend the Rage Crossbow X Mechanical Broadheads. These broadheads are specifically optimized for high-velocity crossbows, offering superior accuracy, deep penetration, and reliable performance on large game. Their innovative design ensures a precise, lethal strike, making them a perfect match for the Killer Instinct Fatal X.
