Build Quality – Durability


Shooting and hunting sessions can stretch over hours, and thus the durability ensured by a crossbow gains considerable importance. Like many other bows from Excalibur, this model does not disappoint as far as its build quality and durability are concerned.

It is enough to take a closer look at this unit to realize that the manufacturer put a lot of care into its construction and chose its various components and materials based on how long and well they can perform.

What makes it stand out is that it can reach up to 400 FPS while keeping a narrow profile, which is another proof that everything that went into the making of this crossbow is not only durable but also committed to ensuring performance every time.



The best spot to shoot your arrow might not always be generous, and here is where the narrow profile of the Excalibur Assassin 400TD scores big. By managing to pack the systems and technology mentioned above in a unit that is compact yet so fast, the manufacturer made it possible for shooters and hunters to target the game of interest even from small blinds or treestands.

The unit is thus easy to maneuver and can be quickly assembled and disassembled, a benefit that holds great importance since every second counts when you’re out there. The item is available in TrueTimber Strata and Realtree Edge and comes with a Sound Deadening System so that you remain unnoticed from a visual and sonic point of view.


Speed and Performance

A crossbow might be easy to use and compact, yet it won’t help you take down the game you’re after if it is not designed for speed and performance. The Excalibur Assassin 400TD is a model that manages to combine an easy-to-use and compact design with blistering speeds of up to 400 FPS.

Given the technology and systems employed for its construction, the product can be used for a variety of shooting and hunting applications. The noteworthy velocities and powerful performance will help you advance your experience and end your hunting sessions successfully.

For example, with just 12 lbs of force, the unit can generate speeds of up 360 FPS and over 100 FPE, which is remarkable considering the compact design of this model. However, keep in mind that the high draw weight might render this item unsuitable for beginners and inexperienced hunters.



The noteworthy speed and performance ensured are further paired with repeatable accuracy hunt after hunt. To deliver such results, the product packs durable components, such as a rifle-grade trigger with a light pull weight that, combined with a clean break, ensures increased accuracy.

You can also adjust the cheekpiece for a perfect fit, and cocking/decocking the unit is easy, quick, and safe, which further enhances the accuracy delivered. The narrow profile and comfortable design also add to all that.




Safety is essential when designing and using a crossbow. The manufacturer took this aspect seriously and thus paired the unit with an anti-dry fire system to prevent accidental firing and keep you safe while employing the item. Furthermore, the integrated silent cocking device ensures easy and safe cocking and decocking.


Noise and Vibration

When using a crossbow to shoot at a target in your backyard, a noisy model might not be that much of a problem, but when you employ it for hunting, every noise might spook the game.

To keep the performance silent, the Excalibur Assassin 400TD comes with a Sound Deadening System that eliminates noise and reduces shock and vibration for a smoother and quieter performance.


Ease Of Use and Assembly

One of the things that render this item suitable even for novices is the ease of use ensured. The product was designed to make it simple even for beginners to cock and decock it and thus comes with an integrated silent cranking aid.

The Quick-Loc Technology takedown system enables you to assemble/disassemble it with ease. However, if you’re completely new to this type of product, the owner manual included will help you find the answers to your questions. There are also online tutorials to help you get all the pieces together.

Achieving the perfect fit and doing so rapidly won’t be a problem as the item comes with an ambidextrous cheekpiece that is adjustable; the Tru-Fit Stock is also fully adjustable.
