My Personal Experience

The first time I laid hands on the Excalibur Assassin 400, I was immediately impressed by its sturdy build and fine craftsmanship – it felt robust, yet well-balanced.

But my appreciation for this crossbow truly deepened once I took it out into the field.

I remember one particular hunting expedition vividly.

It was an early morning in the dense woods, the air heavy with the scent of pine and damp earth.

As a deer grazed peacefully in the clearing, I raised my Assassin 400, appreciating the Tru-Fit Stock that had been adjusted perfectly to my form.

The silence was palpable, interrupted only by the occasional rustle of leaves under the deer's hooves. The S.D.S. Silencing system on the Assassin 400 proved its worth, allowing me to cock the bow without causing any disturbance.

This level of stealth gave me an edge that I had not experienced with other crossbows.

Taking a breath, I looked through the Tact-100 Scope, which provided a crystal clear view of the deer.

The illuminated multiplex crosshair system was a game-changer, highlighting my target even in the low light of dawn.

I adjusted the scope to account for the distance and anticipated velocity. The deer remained unaware of my presence, allowing me to take my time and line up the perfect shot.

The moment of truth came as I gently squeezed the Pro-Shot trigger.

The light pull weight, combined with a crisp and clean break, resulted in an incredibly smooth shot.

The bolt flew true, thanks to the Assassin 400’s accuracy, and in the blink of an eye, it found its mark.

It was in that moment I truly understood the capabilities of the Excalibur Assassin 400.

The seamless blend of power, accuracy, and quietness made it a formidable ally in the wilderness.

The ease with which I could disassemble it for transport and reassemble it when required was the cherry on top, making the Assassin 400 a truly remarkable piece of equipment.

And over time, I've come to appreciate it even more. It's not just its performance in the field, but the durability it's demonstrated despite frequent use, and the confidence of knowing that I have a product backed by a limited lifetime warranty.

The Excalibur Assassin 400 has proven to be a worthy investment, a trusted companion on many a hunting expedition since that memorable day.

At a price tag of $1899.99, the Excalibur Assassin 400 is undoubtedly an investment.

It's a premium-priced crossbow that may initially seem steep for some.

Secondly, the Assassin 400's durability means this is a product designed to last.

The High-Output Express Limbs, reinforced Armor Tips, and overall sturdy construction ensure that this crossbow can withstand the rigors of regular use.

This durability translates to longevity, meaning your initial investment will be spread over many years of use.

The Drawbacks

No product is perfect, and the Excalibur Assassin 400, while exceptional in many ways, does have a few drawbacks worth mentioning.

For one, the price point can be a barrier for some.

While I do believe that the Assassin 400 provides excellent value for the price, it's an investment that may not fit within everyone's budget, particularly for beginners or casual archers.

Another minor issue I personally encountered involved the initial setup.

Despite the Quick-Loc Technology making it easy to disassemble and reassemble the crossbow, I found that the first few attempts at setting it up took a bit longer than I'd expected.

It was a bit of a learning curve, but after a few practice runs, I was able to get the hang of it, and it's been smooth sailing ever since.

Additionally, while the Assassin 400 is lighter than some other models on the market, at 7.9 LB, it can still feel a bit hefty after long periods of use.

During a prolonged hunting trip, I noticed a bit of fatigue after carrying it around all day.

However, this is a minor inconvenience and something that can be mitigated with proper conditioning and breaks.

What are people saying?

The Excalibur Assassin 400 has garnered rave reviews from users who have experienced its performance first-hand.

G Salerno shares that the Assassin 400 TD proved his initial doubts about single-string crossbows wrong, demonstrating remarkable speed and accuracy.

The crossbow enabled him to successfully hunt two doe and a buck from 40 to 50 yards away.

He also mentions the fun of demonstrating to others how quickly the crossbow can be assembled and disassembled.

Another user, J, shares that the Assassin 400 was a fantastic upgrade from his previous Excalibur crossbow, the Phoenix.

He praises the Assassin's smaller size, increased speed, deadly accuracy, and the ease of use of the built-in cocking unit.

The crossbow's compact size makes it fun and easy to shoot offhand, while the ease of changing a worn or broken string gives it a significant advantage over compound limb crossbows.

J also appreciates the clear, easy-to-adjust Tact-100 Scope, and the fact that the Assassin comes as a complete package, including a perfect carrying case and other necessary accessories.

Should You Buy? Concluding the Review

After spending considerable time with the Excalibur Assassin 400, my answer to the question “should you buy?” is a resounding yes.

While it does carry a premium price tag and there are minor drawbacks such as the initial setup learning curve and potential for fatigue during prolonged use, these are far outweighed by the crossbow's benefits.

It's also worth noting that the price is reflective of the quality and advanced technology you're getting, and the minor issues can be easily overcome with a bit of practice and conditioning.

In conclusion, the Excalibur Assassin 400 is a top-tier crossbow that offers exceptional performance and value for money.

Whether you're a seasoned bowhunter, a target shooter, or someone looking to get into the sport, this crossbow is a worthwhile investment that's sure to enhance your archery experience.
